Implementations

impl Interner

pub fn new() -> Self

An empty interner.

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

Intern a name, returning the existing id if it is already known.

pub fn get(&self, name: &str) -> Option<AtomId>

The id for a name, if it has been interned. Does not intern.

pub fn resolve(&self, atom: AtomId) -> Result<&str, DomError>

The name behind an id.

Errors if this interner did not mint the id, which is the only defence against an id that crossed a guest boundary and came back wrong.

pub fn len(&self) -> usize

How many distinct names have been interned.

pub fn is_empty(&self) -> bool

Whether nothing has been interned yet.
