Struct wasmer_wasix::runtime::task_manager::tokio::TokioTaskManager

pub struct TokioTaskManager(_);

A task manager that uses tokio to spawn tasks.

Implementations

impl TokioTaskManager

pub fn new(rt: Handle) -> Self

pub fn runtime_handle(&self) -> Handle

pub fn set_shared(rt: Arc<Runtime>) -> Result<(), Error>

Allows the caller to set the shared runtime that will be used by other async processes within Wasmer

The shared runtime must be set before it is used and can only be set once otherwise this call will fail with an error.

pub fn shared() -> Self

Shared tokio [Runtime] that is used by default.

This exists because a tokio runtime is heavy, and there should not be many independent ones in a process.
