Enum wiggle::wasmtime_crate::Extern

pub enum Extern {
    Func(Func),
    Global(Global),
    Table(Table),
    Memory(Memory),
    Instance(Instance),
    Module(Module),
}

An external item to a WebAssembly module, or a list of what can possibly be exported from a wasm module.

This is both returned from Instance::exports as well as required by Instance::new. In other words, this is the type of extracted values from an instantiated module, and it’s also used to provide imported values when instantiating a module.

Variants

Func(Func)

A WebAssembly func which can be called.

Tuple Fields of Func

0: Func

Global(Global)

A WebAssembly global which acts like a Cell<T> of sorts, supporting get and set operations.

Tuple Fields of Global

0: Global

Table(Table)

A WebAssembly table which is an array of Val reference types.

Tuple Fields of Table

0: Table

Memory(Memory)

A WebAssembly linear memory.

Implementations

impl Extern

pub fn into_func(self) -> Option<Func>

Returns the underlying Func, if this external is a function.

Returns None if this is not a function.

pub fn into_global(self) -> Option<Global>

Returns the underlying Global, if this external is a global.

Returns None if this is not a global.

pub fn into_table(self) -> Option<Table>

Returns the underlying Table, if this external is a table.

Returns None if this is not a table.

pub fn into_memory(self) -> Option<Memory>

Returns the underlying Memory, if this external is a memory.

Returns None if this is not a memory.

pub fn into_instance(self) -> Option<Instance>

Returns the underlying Instance, if this external is a instance.

Returns None if this is not a instance.

pub fn into_module(self) -> Option<Module>

Returns the underlying Module, if this external is a module.

Returns None if this is not a module.

pub fn ty(&self, store: impl AsContext) -> ExternType

Returns the type associated with this Extern.

The store argument provided must own this Extern and is used to look up type information.

Panics

Panics if this item does not belong to the store provided.
