Enum wasmtime::CallHook

source · [−]

pub enum CallHook {
    CallingWasm,
    ReturningFromWasm,
    CallingHost,
    ReturningFromHost,
}

Expand description

Passed to the argument of Store::call_hook to indicate a state transition in the WebAssembly VM.

Variants

`CallingWasm`

Indicates the VM is calling a WebAssembly function, from the host.

`ReturningFromWasm`

Indicates the VM is returning from a WebAssembly function, to the host.

`CallingHost`

Indicates the VM is calling a host function, from WebAssembly.

`ReturningFromHost`

Indicates the VM is returning from a host function, to WebAssembly.

Implementations

source

impl CallHook

source

pub fn entering_host(&self) -> bool

Indicates the VM is entering host code (exiting WebAssembly code)

source

pub fn exiting_host(&self) -> bool

Indicates the VM is exiting host code (entering WebAssembly code)
