Struct wasmtime_runtime::VMCallerCheckedFuncRef

#[repr(C)]
pub struct VMCallerCheckedFuncRef {
    pub func_ptr: NonNull<VMFunctionBody>,
    pub type_index: VMSharedSignatureIndex,
    pub vmctx: *mut VMOpaqueContext,
}

The VM caller-checked “anyfunc” record, for caller-side signature checking. It consists of the actual function pointer and a signature id to be checked by the caller.

Fields

func_ptr: NonNull<VMFunctionBody>

Function body.

type_index: VMSharedSignatureIndex

Function signature id.

vmctx: *mut VMOpaqueContext

The VM state associated with this function.

For core wasm instances this will be *mut VMContext but for the upcoming implementation of the component model this will be something else. The actual definition of what this pointer points to depends on the definition of func_ptr and what compiled it.
