Trait GetTupleField

Source 
pub trait GetTupleField {
    // Required methods
    fn get_field<T: Reflect>(&self, index: usize) -> Option<&T>;
    fn get_field_mut<T: Reflect>(&mut self, index: usize) -> Option<&mut T>;
}
Expand description

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§

Source

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

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

Source

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

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

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
