Struct litemap::LiteMap

pub struct LiteMap<K: ?Sized, V: ?Sized, S = Vec<(K, V)>> { /* private fields */ }

A simple “flat” map based on a sorted vector

See the module level documentation for why one should use this.

The API is roughly similar to that of std::collections::BTreeMap.

Implementations

impl<K, V> LiteMap<K, V>

pub const fn new_vec() -> Self

Construct a new LiteMap backed by Vec

impl<K, V, S> LiteMap<K, V, S>

pub const fn from_sorted_store_unchecked(values: S) -> Self

Construct a new LiteMap using the given values

The store must be sorted and have no duplicate keys.

impl<K, V> LiteMap<K, V, Vec<(K, V)>>

pub fn into_tuple_vec(self) -> Vec<(K, V)>

Convert a LiteMap into a sorted Vec<(K, V)>.

impl<K: ?Sized, V: ?Sized, S> LiteMap<K, V, S>

where S: StoreConstEmpty<K, V>,

pub const fn new() -> Self

Create a new empty LiteMap

impl<K: ?Sized, V: ?Sized, S> LiteMap<K, V, S>

where S: Store<K, V>,

pub fn len(&self) -> usize

The number of elements in the LiteMap

pub fn is_empty(&self) -> bool

Whether the LiteMap is empty

pub fn get_indexed(&self, index: usize) -> Option<(&K, &V)>

Get the key-value pair residing at a particular index

In most cases, prefer LiteMap::get() over this method.

pub fn first(&self) -> Option<(&K, &V)>

Get the lowest-rank key/value pair from the LiteMap, if it exists.

Examples

use litemap::LiteMap;

let mut map =
    LiteMap::<i32, &str, Vec<_>>::from_iter([(1, "uno"), (3, "tres")]);

assert_eq!(map.first(), Some((&1, &"uno")));

pub fn last(&self) -> Option<(&K, &V)>

Get the highest-rank key/value pair from the LiteMap, if it exists.

Examples

Returns a new LiteMap with owned keys and values.

The trait bounds allow transforming most slice and string types.

Examples

use litemap::LiteMap;

let mut map: LiteMap<&str, &str> = LiteMap::new_vec();
map.insert("one", "uno");
map.insert("two", "dos");

let boxed_map: LiteMap<Box<str>, Box<str>> = map.to_boxed_keys_values();

map.insert("one", 11);
map.insert("two", 22);

let boxed_map: LiteMap<Box<str>, usize> = map.to_boxed_keys();

assert_eq!(boxed_map.get("one"), Some(&11));

where K: Borrow<Q>, Q: Ord + ?Sized,

Get the value associated with key, if it exists.

use litemap::LiteMap;

let mut map = LiteMap::new_vec();
map.insert(1, "one");
map.insert(2, "two");
assert_eq!(map.get(&1), Some(&"one"));

where K: Borrow<Q>, Q: Ord + ?Sized,

Obtain the index for a given key, or if the key is not found, the index at which it would be inserted.

(The return value works equivalently to slice::binary_search_by())

The indices returned can be used with Self::get_indexed(). Prefer using Self::get() directly where possible.

impl<K: ?Sized, V: ?Sized, S> LiteMap<K, V, S>

assert_eq!(sub_map.get(&3), Some(&"three"));

pub fn as_sliced(&self) -> LiteMap<K, V, &S::Slice>

where K: Ord, S: StoreMut<K, V>,

pub fn get_mut<Q>(&mut self, key: &Q) -> Option<&mut V>

where K: Borrow<Q>, Q: Ord + ?Sized,

Get the value associated with key, if it exists, as a mutable reference.

use litemap::LiteMap;

let mut map = LiteMap::new_vec();
map.insert(1, "one");
map.insert(2, "two");
if let Some(mut v) = map.get_mut(&1) {
    *v = "uno";
}
assert_eq!(map.get(&1), Some(&"uno"));

pub fn try_append(&mut self, key: K, value: V) -> Option<(K, V)>

Appends value with key to the end of the underlying vector, returning key and value if it failed. Useful for extending with an existing sorted list.

use litemap::LiteMap;

let mut map = LiteMap::new_vec();
assert!(map.try_append(1, "uno").is_none());
assert!(map.try_append(3, "tres").is_none());

assert!(
    matches!(map.try_append(3, "tres-updated"), Some((3, "tres-updated"))),
    "append duplicate of last key",
);

assert!(
    matches!(map.try_append(2, "dos"), Some((2, "dos"))),

assert_eq!(map.get(&2), None);

pub fn insert(&mut self, key: K, value: V) -> Option<V>

Insert value with key, returning the existing value if it exists.

map.insert(2, "two");
assert_eq!(map.get(&1), Some(&"one"));
assert_eq!(map.get(&3), None);

pub fn try_insert(&mut self, key: K, value: V) -> Option<(K, V)>

Attempts to insert a unique entry into the map.

If key is not already in the map, inserts it with the corresponding value and returns None.

If key is already in the map, no change is made to the map, and the key and value are returned back to the caller.

use litemap::LiteMap;

let mut map = LiteMap::new_vec();
map.insert(1, "one");
map.insert(3, "three");

// 2 is not yet in the map...
assert_eq!(map.try_insert(2, "two"), None);
assert_eq!(map.len(), 3);

// ...but now it is.
assert_eq!(map.try_insert(2, "TWO"), Some((2, "TWO")));
assert_eq!(map.len(), 3);

pub fn try_get_or_insert<E>( &mut self, key: K, value: impl FnOnce(&K) -> Result<V, E>, ) -> Result<(usize, &V), E>

Attempts to insert a unique entry into the map.

If key is not already in the map, invokes the closure to compute value, inserts the pair into the map, and returns a reference to the value. The closure is passed a reference to the key argument.

If key is already in the map, a reference to the existing value is returned.

Additionally, the index of the value in the map is returned. If it is not desirable to hold on to the mutable reference’s lifetime, the index can be used to access the element via LiteMap::get_indexed().

The closure returns a Result to allow for a fallible insertion function. If the creation of value is infallible, you can use core::convert::Infallible.

use litemap::LiteMap;

/// Helper function to unwrap an `Infallible` result from the insertion function
fn unwrap_infallible<T>(result: Result<T, core::convert::Infallible>) -> T {
    result.unwrap_or_else(|never| match never {})
}

let mut map = LiteMap::new_vec();
map.insert(1, "one");
map.insert(3, "three");

// 2 is not yet in the map...
let result1 = unwrap_infallible(
    map.try_get_or_insert(2, |_| Ok("two"))
);
assert_eq!(result1.1, &"two");
assert_eq!(map.len(), 3);

// ...but now it is.
let result1 = unwrap_infallible(
    map.try_get_or_insert(2, |_| Ok("TWO"))
);
assert_eq!(result1.1, &"two");
assert_eq!(map.len(), 3);

pub fn remove<Q>(&mut self, key: &Q) -> Option<V>

where K: Borrow<Q>, Q: Ord + ?Sized,

Remove the value at key, returning it if it exists.

use litemap::LiteMap;

let mut map = LiteMap::new_vec();
map.insert(1, "one");
map.insert(2, "two");
assert_eq!(map.remove(&1), Some("one"));
assert_eq!(map.get(&1), None);

impl<K, V, S> LiteMap<K, V, S>

where K: Ord, S: StoreIntoIterator<K, V> + StoreFromIterator<K, V>,

pub fn extend_from_litemap(&mut self, other: Self) -> Option<Self>

Insert all elements from other into this LiteMap.

If other contains keys that already exist in self, the values in other replace the corresponding ones in self, and the rejected items from self are returned as a new LiteMap. Otherwise, None is returned.

The implementation of this function is optimized if self and other have no overlap.

Examples

use litemap::LiteMap;

let mut map1 = LiteMap::new_vec();
map1.insert(1, "one");
map1.insert(2, "two");

let mut map2 = LiteMap::new_vec();
map2.insert(2, "TWO");
map2.insert(4, "FOUR");

let leftovers = map1.extend_from_litemap(map2);

assert_eq!(map1.len(), 3);
assert_eq!(map1.get(&1), Some("one").as_ref());
assert_eq!(map1.get(&2), Some("TWO").as_ref());
assert_eq!(map1.get(&4), Some("FOUR").as_ref());

let map3 = leftovers.expect("Duplicate keys");
assert_eq!(map3.len(), 1);
assert_eq!(map3.get(&2), Some("two").as_ref());

Trait Implementations

impl<K, V, S> Bake for LiteMap<K, V, S>

where S: Bake,

Bakes a LiteMap into Rust code for fast runtime construction from data. Use this impl during code generation, such as in a build.rs script.

For the most efficient bake, bake the LiteMap with a slice store. Use functions such as the following for converting an allocated LiteMap to a borrowing LiteMap:

• LiteMap::to_borrowed_keys()
• LiteMap::to_borrowed_values()
• LiteMap::to_borrowed_keys_values()
• LiteMap::as_sliced()

Examples

use databake::*;
use litemap::LiteMap;

// Construct the LiteMap fully owned and allocated:
let mut litemap_alloc: LiteMap<usize, String, Vec<_>> = LiteMap::new_vec();
litemap_alloc.insert(1usize, "one".to_string());
litemap_alloc.insert(2usize, "two".to_string());
litemap_alloc.insert(10usize, "ten".to_string());

// Convert to a borrowed type for baking:
let litemap_str: LiteMap<usize, &str, Vec<_>> =
    litemap_alloc.to_borrowed_values();
let litemap_slice: LiteMap<usize, &str, &[_]> = litemap_str.as_sliced();

// The bake will now work for const construction:
let mut ctx = Default::default();
println!(
    "const FOO: LiteMap<usize, &str, &[(usize, &str)]> = {};",
    litemap_slice.bake(&mut ctx)
);

fn cmp(&self, other: &LiteMap<K, V, S>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,
