Trait objc2::encode::__unstable::EncodeArguments
source · pub trait EncodeArguments: Sealed {
const ENCODINGS: &'static [Encoding];
}Available on crate feature
unstable-encode-internals only.Expand description
Types that represent an ordered group of function arguments, where each argument has an Objective-C type-encoding, or can be converted from one.
This is implemented for tuples of up to 16 arguments, where each argument
implements EncodeConvertArgument. It is primarily used to make generic
code a bit easier.
Note that tuples themselves don’t implement Encode directly, because
they’re not FFI-safe!
