Implementations§

Source§

impl Interner

Source

pub fn with_capacity(cap: usize) -> Interner

Create an interner with capacity cap (to the next power of two).

Source

pub fn contains(&self, name: &str) -> bool

True if name is an interned symbol.

Source

fn intern_final(&mut self, name: &'static str) -> Interned

Source

pub fn get_if_interned(&self, name: &str) -> Option<Interned>

If name is interned then return it, otherwise None.

Source

pub fn intern_static(&mut self, name: &'static str) -> Interned

Intern name in this interner. Will return the existing symbol if it exists or add it and and return it if not. Use this if you already have a static str reference to avoid wasting space on making another.

Source

pub fn intern(&mut self, name: &str) -> Interned

Intern name in this interner. Will return the existing symbol if it exists or add it and return it if not.

Source

pub fn get_string(&self, interned: Interned) -> Option<&'static str>

Source

pub fn capacity(&self) -> usize

Return the amount of memory allocated by the interner.

Source

pub fn used(&self) -> usize

Return the amount of memory used to store symbols in the interner.

Source

pub fn len(&self) -> usize

Return the number of symbols in the interner.

Source

pub fn is_empty(&self) -> bool

Are there no symbols in this interner?
