Enum Backend Async Function EnvMut &nbsp; Copy item path

Sys(AsyncFunctionEnvMut<T>)

The function environment for the sys runtime.

Implementations§

impl<T: 'static> BackendAsyncFunctionEnvMut<T>

pub async fn read(&self) -> BackendAsyncFunctionEnvHandle<T>

Waits for a store lock and returns a read-only handle to the function environment.

pub async fn write(&self) -> BackendAsyncFunctionEnvHandleMut<T>

Waits for a store lock and returns a mutable handle to the function environment.

pub fn as_ref(&self) -> BackendFunctionEnv<T>

Borrows a new immutable reference

pub fn as_mut(&mut self) -> Self

Borrows a new mutable reference

pub fn as_store_async(&self) -> impl AsStoreAsync + 'static

Creates an AsStoreAsync from this BackendAsyncFunctionEnvMut.

Trait Implementations§

impl<T> From<AsyncFunctionEnvMut<T>> for BackendAsyncFunctionEnvMut<T>

fn from(value: AsyncFunctionEnvMut<T>) -> Self

Converts to this type from the input type.
