Struct wasmer_vm::TlsRestore

source · 
pub struct TlsRestore(_);
Expand description

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

Implementations§

source§

impl TlsRestore

source

pub unsafe fn take() -> Result<Self, Trap>

Takes the TLS state that is currently configured and returns a token that is used to replace it later.

Safety

This is not a safe operation since it’s intended to only be used with stack switching found with fibers and async wasmer.

source

pub unsafe fn replace(self) -> Result<(), Trap>

Restores a previous tls state back into this thread’s TLS.

Safety

This is unsafe because it’s intended to only be used within the context of stack switching within wasmer.
