#[repr(C)]
pub union VMFunctionContext {
pub vmctx: *mut VMContext,
pub host_env: *mut c_void,
}
Expand description
Union representing the first parameter passed when calling a function.
It may either be a pointer to the VMContext
if it’s a Wasm function
or a pointer to arbitrary data controlled by the host if it’s a host function.
Fields§
§vmctx: *mut VMContext
Wasm functions take a pointer to VMContext
.
host_env: *mut c_void
Host functions can have custom environments.
