Trait EncodeArgument 

pub unsafe trait EncodeArgument: Sealed {
    const ENCODING_ARGUMENT: Encoding;
}

Types that are safe as arguments to Objective-C methods.

This is a sealed trait, and should not need to be implemented manually.

Safety

Similar to Encode, except the value is only guaranteed to be valid as an argument or a parameter, both from functions/methods you’re calling and from declared functions/methods.

It does not have to be valid as e.g. an instance variable, or as an argument to a function.

Required Associated Constants

const ENCODING_ARGUMENT: Encoding

The Objective-C type-encoding for this type.

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.

Implementors

impl<T: Encode> EncodeArgument for T

const ENCODING_ARGUMENT: Encoding = T::ENCODING
