Module interrupt_registry 

Implements the necessary infrastructure for interrupting running WASM code via OS signals.

This module is meant to be used from within the wasmer crate. Embedders should not call any of the functions here; instead, they should go through [wasmer::Store::get_interrupter].

Functions

install

Install interrupt state for the given store. Note that this function may be called more than once, and correctly maintains a stack of stores for which the state is installed.

interrupt

Interrupt the store with the given ID. Best effort is made to ensure interrupts are handled. However, there is no guarantee; under rare circumstances, it is possible for the interrupt to be missed. One such case is when the target thread is about to call WASM code but has not yet made the call.

is_interrupted

Returns true if the store with the given ID has already been interrupted.
