Struct wasmtime_runtime::PreviousAsyncWasmCallState

source · 
pub struct PreviousAsyncWasmCallState { /* private fields */ }
Expand description

Opaque state used to help control TLS state across stack switches for async support.

Implementations§

source§

impl PreviousAsyncWasmCallState

source

pub unsafe fn restore(self) -> AsyncWasmCallState

Pops a fiber’s linked list of activations and stores them in AsyncWasmCallState.

This will pop the top activation of this current thread continuously until it reaches whatever the current activation was when push was originally called.

§Unsafety

Must be paired with a push and only performed at a time when a fiber is being suspended.
