Struct wasmtime_runtime::VMRuntimeLimits

#[repr(C)]
pub struct VMRuntimeLimits {
    pub stack_limit: UnsafeCell<usize>,
    pub fuel_consumed: UnsafeCell<i64>,
    pub epoch_deadline: UnsafeCell<u64>,
}

Structure used to control interrupting wasm code.

Fields

stack_limit: UnsafeCell<usize>

Current stack limit of the wasm module.

For more information see crates/cranelift/src/lib.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.

epoch_deadline: UnsafeCell<u64>

Deadline epoch for interruption: if epoch-based interruption is enabled and the global (per engine) epoch counter is observed to reach or exceed this value, the guest code will yield if running asynchronously.
