[−][src]Struct gdnative::prelude::Null

pub struct Null<T>(_);

Represents an explicit null reference in method arguments. This works around type inference issues with Option. You may create Nulls with Null::null or GodotObject::null.

Implementations

impl<T> Null<T> where
    T: GodotObject, [src]

pub fn null() -> Null<T>[src]

Creates an explicitly null reference that can be used as a method argument.
