Trait Param 

pub unsafe trait Param {
    // Required methods
    fn kind() -> ParamKind;
    fn as_ref(&self) -> ParamRef<'_>;
    fn as_mut(&mut self) -> ParamMut<'_>;
}

Helper trait used in the implmenetation of derive macro PluginBase. DO NOT use directly.

Safety

Implementers must verify that the parameter type returned by Param::kind, Param::as_ref and Param::as_mut agrees with each other.

Required Methods

fn kind() -> ParamKind

fn as_ref(&self) -> ParamRef<'_>

fn as_mut(&mut self) -> ParamMut<'_>

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.
