An instantiated instance of the wasi exports.

This represents a wasi module which can be used to instantiate other wasm modules. This structure exports all that various fields of the wasi instance as fields which can be used to implement your own instantiation logic, if necessary. Additionally Wasi::get_export can be used to do name-based resolution.

Implementations

impl Wasi[src]

pub fn new(store: &Store, cx: WasiCtx) -> Self[src]

Creates a new Wasi instance.

External values are allocated into the store provided and configuration of the wasi instance itself should be all contained in the cx parameter.

pub fn get_export(&self, name: &str) -> Option<&Func>[src]

Looks up a field called name in this structure, returning it if found.

This is often useful when instantiating a wasmtime instance where name resolution often happens with strings.

pub fn add_to_linker(&self, linker: &mut Linker) -> Result<()>[src]

Adds all instance items to the specified Linker.
