Struct LabelInterner 

pub struct LabelInterner { /* private fields */ }

Label-text interner. Same shape, separate index space, with slot 0 pre-seeded as the empty string.

Implementations

impl LabelInterner

pub fn new() -> Self

pub fn intern(&mut self, text: &str) -> LabelId

pub fn resolve(&self, ix: LabelId) -> &str

Resolve an index back to its label text.

Panics

Panics if ix did not come from this interner’s intern. Indices are dense and append-only within one LabelInterner instance; they are not portable across instances, and an out-of-range index panics rather than silently returning a wrong or empty string.
