Struct Char16TrieIterator 

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

This struct represents an iterator over a Char16Trie.

Implementations

impl<'a> Char16TrieIterator<'a>

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

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

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);

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);

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);

Trait Implementations

impl<'a> Clone for Char16TrieIterator<'a>

fn clone(&self) -> Char16TrieIterator<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
