Fields

magic: u32

well_known: WellKnown

Pre-cached IDs for “well-known” names.

instructions: NamedIdxMap<Opcode, InstructionDef, KhrSegmented>

operand_kinds: NamedIdxMap<OperandKind, OperandKindDef, Flat>

operand_names: IndexSet<&'static str, BuildHasherDefault<FxHasher>>

ext_inst_sets: BTreeMap<&'static str, (OnceLock<ExtInstSetDesc>, Box<dyn Fn() -> ExtInstSetDesc + Send + Sync>)>

Implementations

impl Spec

pub fn get() -> &'static Spec

Return a lazily-loaded Spec (only does significant work for the first call).

pub fn get_ext_inst_set_by_lowercase_name( &self, lowercase_ext_inst_set_name: &str ) -> Option<&ExtInstSetDesc>

Return a lazily-parsed ExtInstSetDesc, if a known one exists for this OpExtInstImport name (required to be lowercase, due to Khronos’ choice of case insensitivity, but not checked by this function).

fn from_raw(raw_core_grammar: CoreGrammar<'static>) -> Self

Implementation detail of Spec::get, indexes the raw data to produce a Spec.
