§Patchable
A crate for handling partial updates to data structures.
This crate provides the Patchable, Patch, and TryPatch traits, along with
derive macros for Patchable and Patch, and an attribute macro patchable_model
re-exported from patchable_macro for easy derivation.
§Motivation
Many systems receive incremental updates where only a subset of fields change or can be considered part of the state. This crate formalizes this pattern by defining a patch type for a structure and providing a consistent way to apply such patches safely.
Traits§
- Patch
- A type that can be updated using its companion patch.
- Patchable
- A type that declares a companion patch type.
- TryPatch
- A fallible variant of
Patch.
Attribute Macros§
- patchable_
model - Attribute macro that augments a struct with Patchable/Patch derives.
