Trait conch_runtime::env::FunctionEnvironment

pub trait FunctionEnvironment {
    type FnName;
    type Fn;
    fn function(&self, name: &Self::FnName) -> Option<&Self::Fn>;
    fn set_function(&mut self, name: Self::FnName, func: Self::Fn);

    fn has_function(&self, name: &Self::FnName) -> bool { ... }
}

An interface for setting and getting shell functions.

Associated Types

type FnName

The name to be associated with a function.

type Fn

The type of the function.

Required Methods

fn function(&self, name: &Self::FnName) -> Option<&Self::Fn>

Get a particularly named function if it was registered.

fn set_function(&mut self, name: Self::FnName, func: Self::Fn)

Register a shell function with a given name.

Provided Methods

fn has_function(&self, name: &Self::FnName) -> bool

Check if a particularly named function was registered.
