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.

Instance(Instance)

A WebAssembly instance.

Module(Module)

A WebAssembly module.
