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.

Trait Implementations

impl Clone for EntityType

fn clone(&self) -> EntityType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EntityType

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EntityType

fn deserialize<__D>( __deserializer: __D ) -> Result<EntityType, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for EntityType

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TypeTrace for EntityType

fn trace<F, E>(&self, func: &mut F) -> Result<(), E>

where F: FnMut(EngineOrModuleTypeIndex) -> Result<(), E>,

Visit each edge.

fn trace_mut<F, E>(&mut self, func: &mut F) -> Result<(), E>

where F: FnMut(&mut EngineOrModuleTypeIndex) -> Result<(), E>,

Visit each edge, mutably.

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

where F: FnMut(ModuleInternedTypeIndex) -> u32,

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