Trait bevy::reflect::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;
}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§
fn get_field<T>(&self, index: usize) -> Option<&T>where
T: Reflect,
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,
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.
