WritableHashMapEntryView

pub final class WritableHashMapEntryView<K, V>

Borrows a stored map entry with readonly key and writable value access.

Allocates nothing and retains no owner. Structural mutation, move or destruction invalidates both aliases; external synchronization is required. Value-only mutation does not change stored key hash/equality or probe-chain structure. K: Exact borrowed key type. V: Exact borrowed value type.

WritableHashMapEntryView.Key

pub Key: K&;

Readonly stored-key alias; never mutable through iteration.

WritableHashMapEntryView.Value

pub Value: mut V&;

Writable stored-value alias, valid within table stability.
