Trait GetTupleField 

pub trait GetTupleField {
    // Required methods
    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.

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.
