Struct wasmtime_runtime::TlsRestore [−][src]
Opaque state used to help control TLS state across stack switches for async support.
Implementations
impl TlsRestore[src]
pub unsafe fn take() -> TlsRestore[src]
Takes the TLS state that is currently configured and returns a token that is used to replace it later.
This is not a safe operation since it’s intended to only be used with stack switching found with fibers and async wasmtime.
pub unsafe fn replace(self) -> Result<(), Trap>[src]
Restores a previous tls state back into this thread’s TLS.
This is unsafe because it’s intended to only be used within the context of stack switching within wasmtime.
