Struct icu::experimental::unicodeset_parse::VariableMap

pub struct VariableMap<'a>(/* private fields */);

The map used for parsing UnicodeSets with variable support. See parse_with_variables.

Implementations

impl<'a> VariableMap<'a>

pub fn new() -> VariableMap<'a>

Creates a new empty map.

pub fn remove(&mut self, key: &str) -> Option<VariableValue<'a>>

Removes a key from the map, returning the value at the key if the key was previously in the map.

pub fn get(&self, key: &str) -> Option<&VariableValue<'a>>

Get a reference to the value associated with this key, if it exists.

pub fn insert( &mut self, key: String, value: VariableValue<'a>, ) -> Result<(), &VariableValue<'_>>

Insert a VariableValue into the VariableMap.

Returns Err with the old value, if it exists, and does not update the map.

pub fn insert_char( &mut self, key: String, c: char, ) -> Result<(), &VariableValue<'_>>

Insert a char into the VariableMap.

Returns Err with the old value, if it exists, and does not update the map.

pub fn insert_string( &mut self, key: String, s: String, ) -> Result<(), &VariableValue<'_>>

Insert a String of any length into the VariableMap.

Returns Err with the old value, if it exists, and does not update the map.

pub fn insert_str( &mut self, key: String, s: &'a str, ) -> Result<(), &VariableValue<'_>>

Insert a &str of any length into the VariableMap.

Returns Err with the old value, if it exists, and does not update the map.

pub fn insert_set( &mut self, key: String, set: CodePointInversionListAndStringList<'a>, ) -> Result<(), &VariableValue<'_>>

Insert a CodePointInversionListAndStringList into the VariableMap.

Returns Err with the old value, if it exists, and does not update the map.

Trait Implementations

impl<'a> Clone for VariableMap<'a>

fn clone(&self) -> VariableMap<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for VariableMap<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'a> Default for VariableMap<'a>

fn default() -> VariableMap<'a>

Returns the “default value” for a type.
