Struct GlobalInterner 

pub struct GlobalInterner { /* private fields */ }

Thread-safe global string interner.

Strings interned here live for the lifetime of the program. Use this for identifiers that appear frequently across many queries.

Implementations

impl GlobalInterner

pub fn get() -> &'static Self

Get the global interner instance.

pub fn intern(&self, s: &str) -> InternedStr

Intern a string, returning an interned reference.

If the string has been interned before, returns the existing reference. Otherwise, creates a new interned entry.

pub fn lookup(&self, s: &str) -> Option<InternedStr>

Try to get an already-interned string without creating a new entry.

pub fn len(&self) -> usize

Get the number of interned strings.

pub fn is_empty(&self) -> bool

Check if the interner is empty.

pub fn stats(&self) -> InternerStats

Get interning statistics.

pub fn clear(&self)

Clear all interned strings (use with caution!).

This invalidates all existing InternedStr references from this interner. Only use during testing or shutdown.
