pub struct AsyncWasiModule { /* private fields */ }

Available on crate feature async and Linux only.

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<&str>>, envs: Option<Vec<(&str, &str)>>, preopens: Option<Vec<(PathBuf, PathBuf)>> ) -> WasmEdgeResult<Self>

Creates a AsyncWasiModule instance.

Arguments

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

• envs - The environment variables.

• preopens - The directories to pre-open.

Error

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

pub fn create_from_wasi_context(wasi_ctx: WasiCtx) -> WasmEdgeResult<Self>

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.
