pub trait GetField {
// Required methods

fn get_field_mut<T>(&mut self, name: &str) -> Option<&mut T>

}Expand description
A convenience trait which combines fetching and downcasting of struct fields.
Example
use bevy_reflect::{GetField, Reflect};
#[derive(Reflect)]
struct Foo {
bar: String,
}
let mut foo = Foo { bar: "Hello, world!".to_string() };
foo.get_field_mut::<String>("bar").unwrap().truncate(5);
assert_eq!(foo.get_field::<String>("bar"), Some(&"Hello".to_string()));Required Methods§
fn get_field<T>(&self, name: &str) -> Option<&T>where
T: Reflect,
fn get_field<T>(&self, name: &str) -> Option<&T>where T: Reflect,
Returns a reference to the value of the field named name, downcast to
T.
fn get_field_mut<T>(&mut self, name: &str) -> Option<&mut T>where
T: Reflect,
fn get_field_mut<T>(&mut self, name: &str) -> Option<&mut T>where T: Reflect,
Returns a mutable reference to the value of the field named name,
downcast to T.
