Module kptrait 

Keypath extensions for crate::Kp: chaining, coercion, and higher-order helpers.

Core read/write traits live in key_paths_core. This module adds Kp-specific APIs.

Traits

AccessorTrait

Optional-root and fallback helpers built on Readable / Writable.

ChainExt

CoercionTrait

HofTrait

KeyPath

A keypath that supports both read and write navigation.

KeyPathValueTarget

Used so async chaining can infer the referent of a reference-valued step (e.g. &T and &mut T both map to T).

KpTrait

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

Readable

Read-only keypath: navigate from Root to Value.

Writable

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