Trait KeyStorage

pub(crate) trait KeyStorage<K>:
    Copy
    + Zero
    + Not<Output = Self>
    + TryFrom<K>
    + TryInto<K>
where
    K: Key,
{
    // Provided methods
    fn from_key(k: K) -> Self { ... }
    fn into_key(self) -> K { ... }
}

Backing storage for a specific key type

Intended to be smaller than or equal in size to the full Key type.

Provided Methods

fn from_key(k: K) -> Self

Fit the indicated key into a KeyStorage, wrapping if necessary.

It is normal for keys to accumulate additional insignificant bits on the left side as we compute sums.

fn into_key(self) -> K

Unpack this KeyStorage back into a Key type, without changing its value.

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.
