Struct Char16TrieIterator

Source

pub struct Char16TrieIterator<'a> { /* private fields */ }

Expand description

This struct represents an iterator over a Char16Trie.

Implementations§

Source §

impl<'a> Char16TrieIterator<'a>

Source

pub fn new(trie: &'a ZeroSlice<u16>) -> Self

Returns a new Char16TrieIterator backed by borrowed data for the trie array

Source

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);

Source

pub fn next32(&mut self, c: u32) -> 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);

Source

pub fn next16(&mut self, c: u16) -> 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.next16('a' as u16);
assert_eq!(res, TrieResult::Intermediate(1));
let res = iter.next16('b' as u16);
assert_eq!(res, TrieResult::FinalValue(100));
let res = iter.next16('c' as u16);
assert_eq!(res, TrieResult::NoMatch);
