Module keypath 

Re-export keypath types for state/action focusing (see optics).

Structs

EnumKp

EnumKp - A keypath for enum variants that supports both extraction and embedding Leverages the existing Kp architecture where optionals are built-in via Option

Kp

Kp — typed keypath with getter/setter closures. See also AKp for type-erased keypaths.

Traits

FieldDiff

State types implement this so subscribers can detect which fields changed by comparing per-field hashes — never by cloning the whole value.

KeyPath

A keypath that supports both read and write navigation.

KpTrait

Logical root/value type identity and composition for a keypath.

Readable

Read-only keypath: navigate from Root to Value.

RefKpTrait

Reference-shaped KpTrait (Root = &R, Value = &V) with HRTB navigation.

Writable

Mutable keypath: setter path (same semantics as a get_mut closure on many keypath APIs).

Functions

hash_value

Hash any Hash value without cloning it.

Type Aliases

EnumKpType

EnumValueKpType

Casepath whose payload is extracted by value (cloned) rather than by reference.
