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()));

Required Methods§

source

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.

source

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.

Object Safety§

This trait is not object safe.
