Trait KeyExt 

pub trait KeyExt: Sized {
    // Required method
    fn write_key(&mut self) -> &mut DiffKey;

    // Provided method
    fn key(self, key: impl Hash) -> Self { ... }
}

Trait for giving an element a stable identity across renders.

Required Methods

fn write_key(&mut self) -> &mut DiffKey

Returns a mutable reference to the element’s diff key.

Provided Methods

fn key(self, key: impl Hash) -> Self

Assign a key derived from any hashable value, used to reconcile elements in dynamic lists.

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.
