Expand description
This struct represents an iterator over a Char16Trie
.
Implementations§
source§impl<'a> Char16TrieIterator<'a>
impl<'a> Char16TrieIterator<'a>
sourcepub fn new(trie: &'a ZeroSlice<u16>) -> Char16TrieIterator<'a>
pub fn new(trie: &'a ZeroSlice<u16>) -> Char16TrieIterator<'a>
Returns a new Char16TrieIterator
backed by borrowed data for the trie
array
sourcepub fn next(&mut self, c: char) -> TrieResult
pub fn next(&mut self, c: char) -> TrieResult
Traverses the trie from the current state for this input char.
§Examples
use icu::collections::char16trie::{Char16Trie, TrieResult};
use zerovec::ZeroVec;
// A Char16Trie containing the ASCII characters 'a' and 'b'.
let trie_data = [48, 97, 176, 98, 32868];
let trie = Char16Trie::new(ZeroVec::from_slice_or_alloc(&trie_data));
let mut iter = trie.iter();
let res = iter.next('a');
assert_eq!(res, TrieResult::Intermediate(1));
let res = iter.next('b');
assert_eq!(res, TrieResult::FinalValue(100));
let res = iter.next('c');
assert_eq!(res, TrieResult::NoMatch);
sourcepub fn next32(&mut self, c: u32) -> TrieResult
pub fn next32(&mut self, c: u32) -> TrieResult
Traverses the trie from the current state for this input char.
§Examples
