Struct icu_collections::char16trie::trie::Char16TrieIterator
source · pub struct Char16TrieIterator<'a> {
trie: &'a ZeroSlice<u16>,
pos: Option<usize>,
remaining_match_length: Option<usize>,
}
Expand description
This struct represents an iterator over a Char16Trie
.
Fields§
§trie: &'a ZeroSlice<u16>
A reference to the Char16Trie data to iterate over.
pos: Option<usize>
Index of next trie unit to read, or None
if there are no more matches.
remaining_match_length: Option<usize>
Remaining length of a linear-match node, minus 1, or None
if not in
such a node.
Implementations§

impl<'a> Char16TrieIterator<'a>
sourcepub fn new(trie: &'a ZeroSlice<u16>) -> Self
pub fn new(trie: &'a ZeroSlice<u16>) -> Self
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.
