Trait implemented by a plugin function.

This trait should not be used directly.

Required Methods

fn call( &self, context: Option<NativeCallContext<'_>>, args: &mut [&mut Dynamic], ) -> Result<Dynamic, Box<EvalAltResult>>

Call the plugin function with the arguments provided.

fn is_method_call(&self) -> bool

Is this plugin function a method?

fn has_context(&self) -> bool

Does this plugin function contain a NativeCallContext parameter?

Provided Methods

fn is_pure(&self) -> bool

Is this plugin function pure?

Defaults to true such that any old implementation that has constant-checking code inside the function itself will continue to work.

fn is_volatile(&self) -> bool

Is this plugin function volatile?

A volatile function is not guaranteed to return the same result for the same input(s).

Defaults to true such that any old implementation that has constant-checking code inside the function itself will continue to work.
