Struct VMCallerCheckedAnyfunc 

#[repr(C)]
pub struct VMCallerCheckedAnyfunc {
    pub func_ptr: *const VMFunctionBody,
    pub type_signature_hash: VMSignatureHash,
    pub vmctx: VMFunctionContext,
    pub call_trampoline: VMTrampoline,
}

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: *const VMFunctionBody

Function body.

type_signature_hash: VMSignatureHash

Function signature id.

vmctx: VMFunctionContext

Function VMContext or host env.

call_trampoline: VMTrampoline

Address of the function call trampoline to invoke this function using a dynamic argument list.

impl PartialEq for VMCallerCheckedAnyfunc

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
