Enum wiggle::wasmtime_crate::Extern

source · [−]

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

Expand description

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.

`Global(Global)`

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

`Table(Table)`

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

`Memory(Memory)`

A WebAssembly linear memory.

Implementations

source

impl Extern

source

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.

source

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.

source

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.

source

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.

source

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.
