Struct wasmtime_runtime::VMInterrupts

#[repr(C)]
pub struct VMInterrupts {
    pub stack_limit: AtomicUsize,
    pub fuel_consumed: UnsafeCell<i64>,
}

Structure used to control interrupting wasm code.

Fields

stack_limit: AtomicUsize

Current stack limit of the wasm module.

This is used to control both stack overflow as well as interrupting wasm modules. For more information see crates/environ/src/cranelift.rs.

fuel_consumed: UnsafeCell<i64>

Indicator of how much fuel has been consumed and is remaining to WebAssembly.

This field is typically negative and increments towards positive. Upon turning positive a wasm trap will be generated. This field is only modified if wasm is configured to consume fuel.
