Trait Builtin 

pub trait Builtin: FromArgs {
    // Required method
    fn call(self, ctx: &BuiltinContext<'_>) -> Result<RValue, RError>;
}

A trait-based builtin function.

Implementors define their arguments as a struct with #[derive(FromArgs)], then implement Builtin::call to execute the function body.

Required Methods

fn call(self, ctx: &BuiltinContext<'_>) -> Result<RValue, RError>

Execute the builtin with decoded arguments.

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.
