Trait ParamType

pub trait ParamType: GodotType {
    // Required method
    fn owned_to_arg<'v>(self) -> Self::Arg<'v>;
}
Expand description

Implemented for all parameter types T that are allowed to receive impl AsArg<T>.

Required Methods§

fn owned_to_arg<'v>(self) -> Self::Arg<'v>

Converts an owned value to the canonical argument type, which can be passed to impl AsArg<T>.

Useful in generic contexts where only a value is available, and one doesn’t want to dispatch between value/reference.

You should not rely on the exact return type, as it may change in future versions; treat it like impl AsArg<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.
