Enum FunctionBody 

pub enum FunctionBody {
    Pointer(fn(&mut Context, &Registry)),
    Closure(Arc<dyn Fn(&mut Context, &Registry) + Send + Sync>),
}

The code a function runs.

Both variants take the context to move data through and the registry to look up anything else they need to call.

Variants

Pointer(fn(&mut Context, &Registry))

A plain function pointer.

Closure(Arc<dyn Fn(&mut Context, &Registry) + Send + Sync>)

A closure, for bodies that capture state such as a compiled script.

Implementations

impl FunctionBody

pub fn pointer(pointer: fn(&mut Context, &Registry)) -> Self

Wraps a function pointer.

pub fn closure<T>(closure: T) -> Self

where T: Fn(&mut Context, &Registry) + Send + Sync + 'static,

Wraps a closure.

pub fn invoke(&self, context: &mut Context, registry: &Registry)

Runs the body. Prefer Function::invoke, which also scopes registers.

Trait Implementations

impl Debug for FunctionBody

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
