Trait swift_rs::SwiftArg

pub trait SwiftArg<'a> {
    type ArgType;

    // Required method
    unsafe fn as_arg(&'a self) -> Self::ArgType;
}

Identifies a type as being a valid argument in a Swift function.

Required Associated Types

type ArgType

Required Methods

unsafe fn as_arg(&'a self) -> Self::ArgType

Creates a swift-compatible version of the argument. For primitives this just returns self, but for SwiftObject types it wraps them in SwiftRef.

This function is called within the swift! macro.

Safety

Creating a SwiftRef is inherently unsafe, but is reliable if using the swift! macro, so it is not advised to call this function manually.
