[−][src]Struct wasi_process::WasiProcess

#[must_use =
  "WasiProcess does nothing without being polled or spawned. Try calling `.spawn()`"]pub struct WasiProcess {
    pub stdin: Option<WasiStdin>,
    pub stdout: Option<WasiStdout>,
    pub stderr: Option<WasiStderr>,
    // some fields omitted
}

A wasi process. See crate documentation for more details and examples.

Fields

stdin: Option<WasiStdin>

An stdin reader for the wasi process

stdout: Option<WasiStdout>

An stdout writer for the wasi process

stderr: Option<WasiStderr>

An stderr writer for the wasi process

Implementations

`impl WasiProcess`[src]

`pub fn new( instance: &Instance, buf_size: MaxBufSize ) -> Result<Self, ExportError>`[src]

Create a WasiProcess from a wasm instance. See the crate documentation for more details. Returns an error if the instance doesn't have a _start function exported.

`pub fn with_function(start_function: Function, buf_size: MaxBufSize) -> Self`[src]

Create a WasiProcess from a wasm instance, given a _start function. See the crate documentation for more details.

`pub fn spawn(self) -> SpawnHandleⓘNotable traits for SpawnHandle impl Future for SpawnHandle type Output = Result<(), SpawnError>;`[src]

Spawn the process on a tokio task. It's okay to let this drop; that just means that you don't care about exactly when or how the process finishes, and you'll know you're done when an stdio stream closes;

Trait Implementations

`impl Future for WasiProcess`[src]

`type Output = Result<(), RuntimeError>`

The type of value produced on completion.

`pub fn poll( mut self: Pin<&mut Self>, cx: &mut Context<'_> ) -> Poll<Self::Output>`[src]
