Struct Interner 

pub struct Interner { /* private fields */ }

Node-id interner. to_id is the single place id Strings live.

Implementations

impl Interner

pub fn new() -> Self

pub fn intern(&mut self, id: &str) -> NodeIndex

pub fn get(&self, id: &str) -> Option<NodeIndex>

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

Resolve an index back to its id string.

Panics

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

pub fn kind(&self, ix: NodeIndex) -> IdKind

Look up the kind classified for ix at intern time.

Panics

Panics if ix did not come from this interner’s intern/get — see Interner::resolve.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
