Implementations

impl StringInterner

pub fn new() -> Self

Creates a new string interner.

pub fn intern(&self, s: &str) -> Arc<str>

Interns a string slice, returning an Arc.

If the string has been interned before, returns the existing Arc. Otherwise, creates a new entry and returns it.

pub fn intern_owned(&self, s: String) -> Arc<str>

Interns an owned String, returning an Arc.

More efficient than intern when you already have an owned String.

pub fn len(&self) -> usize

Returns the number of interned strings.

pub fn is_empty(&self) -> bool

Returns true if no strings have been interned.
