}Expand description
A reflected Rust tuple.
This trait is automatically implemented for arbitrary tuples of up to 12
elements, provided that each element implements Reflect.
Example
use bevy_reflect::Tuple;
let foo = ("blue".to_string(), 42_i32);
assert_eq!(foo.field_len(), 2);
let first = foo.field(0).unwrap();
assert_eq!(first.downcast_ref::<String>(), Some(&"blue".to_string()));Required Methods
Returns a reference to the value of the field with index index as a
&dyn Reflect.
Returns a mutable reference to the value of the field with index index
as a &mut dyn Reflect.
fn iter_fields(&self) -> TupleFieldIter<'_>ⓘNotable traits for TupleFieldIter<'a>impl<'a> Iterator for TupleFieldIter<'a> type Item = &'a (dyn Reflect + 'static);
fn iter_fields(&self) -> TupleFieldIter<'_>ⓘNotable traits for TupleFieldIter<'a>impl<'a> Iterator for TupleFieldIter<'a> type Item = &'a (dyn Reflect + 'static);
Returns an iterator over the values of the tuple’s fields.
fn clone_dynamic(&self) -> DynamicTuple
fn clone_dynamic(&self) -> DynamicTuple
Clones the struct into a DynamicTuple.
