Struct Key 

pub struct Key { /* private fields */ }

Represents the (optional) key of Yew’s virtual nodes.

Keys are cheap to clone (a single u64 copy) and to compare (a single integer comparison). Internally a key stores a hash of the value it was created from, so no heap allocation is required for numeric types in release builds.

In debug builds the original string representation is kept alongside the hash, enabling better diagnostics.

Type-aware hashing

Keys created from different types are not equal even when their string representations coincide. For example Key::from("1") and Key::from(1u64) are distinct.

impl ImplicitClone for Key

fn implicit_clone(&self) -> Self

This function is not magic; it is literally defined as

impl Ord for Key

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl PartialEq for Key

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
