Method verify_message

src/message/mod.rs:99–103

Verifies that the argument and return types match the encoding of the method for the given selector. This will look up the encoding of the method for the given selector, `sel`, and return a `MessageError` if any encodings differ for the arguments `A` and return type `R`. # Example ``` no_run # #[macro_use] extern crate objc; # use objc::runtime::{BOOL, Class, Obje

(&self, sel: Sel)

    ```
