Struct TrieSetOwned

pub struct TrieSetOwned { /* private fields */ }

An owned trie set.

Implementations

impl TrieSetOwned

pub fn from_scalars<I, C>(scalars: I) -> Result<TrieSetOwned>

where I: IntoIterator<Item = C>, C: Borrow<char>,

Create a new trie set from a set of Unicode scalar values.

This returns an error if a set could not be sufficiently compressed to fit into a trie.

pub fn from_codepoints<I, C>(codepoints: I) -> Result<TrieSetOwned>

where I: IntoIterator<Item = C>, C: Borrow<u32>,

Create a new trie set from a set of Unicode scalar values.

This returns an error if a set could not be sufficiently compressed to fit into a trie. This also returns an error if any of the given codepoints are greater than 0x10FFFF.

pub fn as_slice(&self) -> TrieSetSlice<'_>

Return this set as a slice.

pub fn contains_char(&self, c: char) -> bool

Returns true if and only if the given Unicode scalar value is in this set.

pub fn contains_u32(&self, cp: u32) -> bool

Returns true if and only if the given codepoint is in this set.

If the given value exceeds the codepoint range (i.e., it’s greater than 0x10FFFF), then this returns false.
