Enum wasmtime_environ::EntityType

pub enum EntityType {
    Global(Global),
    Memory(Memory),
    Tag(Tag),
    Table(Table),
    Function(EngineOrModuleTypeIndex),
}

A type of an item in a wasm module where an item is typically something that can be exported.

Variants

Global(Global)

A global variable with the specified content type

Memory(Memory)

A linear memory with the specified limits

Tag(Tag)

An event definition.

Table(Table)

A table with the specified element type and limits

Function(EngineOrModuleTypeIndex)

A function type where the index points to the type section and records a function signature.

fn canonicalize_for_runtime_usage<F>(&mut self, module_to_engine: &mut F)

where F: FnMut(ModuleInternedTypeIndex) -> VMSharedTypeIndex,

Canonicalize self by rewriting all type references inside self from module-level interned type indices to engine-level interned type indices.

fn is_canonicalized_for_runtime_usage(&self) -> bool

fn canonicalize_for_hash_consing<F>( &mut self, rec_group_range: Range<ModuleInternedTypeIndex>, module_to_engine: &mut F, )

where F: FnMut(ModuleInternedTypeIndex) -> VMSharedTypeIndex,

Canonicalize self by rewriting all type references inside self from module-level interned type indices to either engine-level interned type indices or recgroup-relative indices.

fn is_canonicalized_for_hash_consing(&self) -> bool

Is this type canonicalized for hash consing?
