Enum EngineOrModuleTypeIndex

source
pub enum EngineOrModuleTypeIndex {
    Engine(VMSharedTypeIndex),
    Module(ModuleInternedTypeIndex),
    RecGroup(RecGroupRelativeTypeIndex),
}
Expand description

An interned type index, either at the module or engine level.

Roughly equivalent to wasmparser::UnpackedIndex, although doesn’t have to concern itself with recursion-group-local indices.

Variants§

§

Engine(VMSharedTypeIndex)

An index within an engine, canonicalized among all modules that can interact with each other.

§

Module(ModuleInternedTypeIndex)

An index within the current Wasm module, canonicalized within just this current module.

§

RecGroup(RecGroupRelativeTypeIndex)

An index within the containing type’s rec group. This is only used when hashing and canonicalizing rec groups, and should never appear outside of the engine’s type registry.
