Struct AsyncWasiModule

pub struct AsyncWasiModule(/* private fields */);

A AsyncWasiModule is a module instance for the WASI specification and used in the async scenario.

Implementations

impl AsyncWasiModule

pub fn create( args: Option<Vec<impl AsRef<str>>>, envs: Option<Vec<(impl AsRef<str>, impl AsRef<str>)>>, ) -> Result<AsyncWasiModule, Box<WasmEdgeError>>

Creates a AsyncWasiModule instance.

Arguments

• args - The commandline arguments. The first argument is the program name.

• envs - The environment variables.

Error

If fail to create a AsyncWasiModule instance, then an error is returned.

pub fn create_from_wasi_context( wasi_ctx: WasiCtx, ) -> Result<AsyncWasiModule, Box<WasmEdgeError>>

Creates a AsyncWasiModule instance with the given wasi context.

Arguments

• wasi_ctx - The WasiCtx instance.

Error

If fail to create AsyncWasiModule instance, then an error is returned.

pub fn name(&self) -> &str

Returns the name of the module instance.

pub fn exit_code(&self) -> u32

Returns the WASI exit code.

The WASI exit code can be accessed after running the “_start” function of a wasm32-wasi program.

Trait Implementations

impl AsMut<AsyncImportObject<WasiCtx>> for AsyncWasiModule

fn as_mut(&mut self) -> &mut AsyncImportObject<WasiCtx>

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<AsyncImportObject<WasiCtx>> for AsyncWasiModule

fn as_ref(&self) -> &AsyncImportObject<WasiCtx>

Converts this type into a shared reference of the (usually inferred) input type.

impl Debug for AsyncWasiModule

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

Formats the value using the given formatter.
