Trait bevy::reflect::GetTupleField

pub trait GetTupleField {
    fn get_field<T>(&self, index: usize) -> Option<&T>
    where
        T: Reflect;
    fn get_field_mut<T>(&mut self, index: usize) -> Option<&mut T>
    where
        T: Reflect;
}

A convenience trait which combines fetching and downcasting of tuple fields.

Example

use bevy_reflect::GetTupleField;

let foo = ("blue".to_string(), 42_i32);

assert_eq!(foo.get_field::<String>(0), Some(&"blue".to_string()));
assert_eq!(foo.get_field::<i32>(1), Some(&42));

Required Methods

fn get_field<T>(&self, index: usize) -> Option<&T> where
    T: Reflect, 

Returns a reference to the value of the field with index index, downcast to T.

fn get_field_mut<T>(&mut self, index: usize) -> Option<&mut T> where
    T: Reflect, 

Returns a mutable reference to the value of the field with index index, downcast to T.
