pub trait SwiftArg<'a> {
type ArgType;
// Required method
unsafe fn as_arg(&'a self) -> Self::ArgType;
}Expand description
Identifies a type as being a valid argument in a Swift function.
Required Associated Types§
Required Methods§
Sourceunsafe fn as_arg(&'a self) -> Self::ArgType
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.
