Struct peepmatic_runtime::paths::PathInterner

pub struct PathInterner { /* fields omitted */ }

An interner and de-duplicator for Paths.

Can be serialized and deserialized while maintaining the same id to interned path mapping.

Implementations

impl PathInterner

pub fn new() -> Self

Construct a new, empty PathInterner.

pub fn intern<'a>(&mut self, path: Path<'a>) -> PathId

Intern a path into this PathInterner, returning its canonical PathId.

If we've already interned this path before, then the existing id we already assigned to it is returned. If we've never seen this path before, then it is copied into this PathInterner and a new id is assigned to it.

pub fn lookup<'a>(&'a self, id: PathId) -> Path<'a>

Lookup a previously interned path by id.
