So calling `x()` results +in a virtual call, whereas `foo()` is statically dispatched, because the type +of `foo` tells us precisely what function is being called. + +As noted above, coercions mean that most code doesn't have to be +concerned with this distinction. However, you can tell the difference +when using **transmute** to convert a fn item into a fn pointer. + +This is sometimes done as part of an FFI: + +```compile_fail,E0591 +extern "C" fn foo(userdata: Box<i32>) { + /* ... */ +} + +# fn callback(_: extern "C" fn(*mut i32)) {} +# use std::mem::transmute; +# unsafe { +let f: extern "C" fn(*mut i32) = transmute(foo); +callback(f); +# } +``` + +Here, transmute is being used to convert the types of the fn arguments. +This pattern is incorrect because, because the type of `foo` is a function +**item** (`typeof(foo)`), which is zero-sized, and the target type (`fn()`) +is a function pointer, which is not zero-sized. +This pattern should be rewritten. There are a few possible ways to do this: + +- change the original fn declaration to match the expected signature, + and do the cast in the fn body (the preferred option) +- cast the fn item fo a fn pointer before calling transmute, as shown here: + + ``` + # extern "C" fn foo(_: Box<i32>) {} + # use std::mem::transmute; + # unsafe { + let f: extern "C" fn(*mut i32) = transmute(foo as extern "C" fn(_)); + let f: extern "C" fn(*mut i32) = transmute(foo as usize); // works too + # } + ``` + +The same applies to transmutes to `*mut fn()`, which were observed in practice. +Note though that use of this type is generally incorrect. +The intention is typically to describe a function pointer, but just `fn()` +alone suffices for that. `*mut fn()` is a pointer to a fn pointer. +(Since these values are typically just passed to C code, however, this rarely +makes a difference in practice.) + +[rfc401]: https://github.com/rust-lang/rfcs/blob/master/text/0401-coercions.md +"##, + +E0512: r##" +Transmute with two differently sized types was attempted.
