source ·

pub trait GetTupleStructField {

Expand description

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

§Example

use bevy_reflect::{GetTupleStructField, Reflect};

#[derive(Reflect)]
struct Foo(String);

let mut foo = Foo("Hello, world!".to_string());

foo.get_field_mut::<String>(0).unwrap().truncate(5);
assert_eq!(foo.get_field::<String>(0), Some(&"Hello".to_string()));
