Struct StaticInterner 

pub struct StaticInterner { /* private fields */ }

Frozen static-string interner. Built once at scanner construction; cloneable via Arc so every rayon worker shares one read-only instance.

index maps each interned string to its slot in arena; it is read-only after construction, so concurrent lookups need no synchronization. The ahash hasher gives a single fast (8-byte-word, hardware-mixed) hash per lookup instead of the CHD perfect hash’s three per-byte hash passes.

Implementations

impl StaticInterner

pub fn from_detector_strings<I, S>(detector_strings: I) -> Self

where I: IntoIterator<Item = S>, S: AsRef<str>,

Build an interner from the universe of stable strings: detector metadata fields + the seed source-type list. Duplicates are collapsed automatically (the map keeps one entry per distinct key).

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

Single-hash lookup. Returns a clone of the pre-allocated Arc<str> when s is in the interner; None otherwise. One ahash pass over the key plus a bucket compare - no second hash, no separate verify pass. Arc<str>: Borrow<str> makes get(s) allocation-free on hits.

pub fn len(&self) -> usize

Number of pre-interned strings.

pub fn is_empty(&self) -> bool

Trait Implementations

impl Default for StaticInterner

fn default() -> StaticInterner

Returns the “default value” for a type.
