Trait Encode

pub unsafe trait Encode {
    const ENCODING: Encoding<'static>;
}

Types that have an Objective-C type encoding.

Unsafe because Objective-C will make assumptions about the type (like its size and alignment) from its encoding, so the implementer must verify that the encoding is accurate.

Required Associated Constants

const ENCODING: Encoding<'static>

Returns the Objective-C type encoding for Self.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
