Struct LiteralTable 

pub struct LiteralTable { /* private fields */ }

Query-scoped table of literal text + optional language tag / datatype IRI, hash -> (text, lang?, datatype?), built by the parser for string/geometry/typed constants. Lives outside the zero-heap SparqlQueryContext — a cold parse/eval-time structure — so builtins (STR/LANG/DATATYPE/geof:*/…) recover what they need without heap on the §6 hot path.

Implementations

impl LiteralTable

pub fn new() -> Self

pub fn intern(&mut self, hash: u64, text: &str)

Record the text for a plain literal hash (idempotent, no lang/datatype).

pub fn intern_tagged( &mut self, hash: u64, text: &str, lang: Option<&str>, datatype: Option<&str>, )

Record a literal with an optional language tag and/or datatype IRI.

pub fn resolve(&self, hash: u64) -> Option<&str>

pub fn lang(&self, hash: u64) -> Option<&str>

The language tag of an interned literal, if it has one.

pub fn datatype(&self, hash: u64) -> Option<&str>

The datatype IRI of an interned literal, if it was tagged with one.

pub fn contains(&self, hash: u64) -> bool

Whether this hash names a known (interned) literal.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
