Struct SimpleFunction 

pub struct SimpleFunction { /* private fields */ }

A function implemented by a plain function pointer plus its descriptor.

This is the explicit registration mechanism used by the numerical modules: no macro framework, no hidden behaviour. The descriptor is the authoritative schema; the engine validates arguments against it before Function::invoke is called.

Implementations

impl SimpleFunction

pub fn new( descriptor: FunctionDescriptor, invoke: fn(&Args, &ExecContext) -> Result<Outcome, EngineError>, ) -> SimpleFunction

pub fn arc( descriptor: FunctionDescriptor, invoke: fn(&Args, &ExecContext) -> Result<Outcome, EngineError>, ) -> Arc<dyn Function>
