Discover Rust Type Reflection with Facet: Inspect, Serialize, and Deserialize Like Never Before

Are you searching for a robust way to perform Rust type reflection in const contexts, enabling powerful introspection and manipulation of your data structures? Look no further! facet provides the tools you need to deeply understand and interact with Rust types. This guide will break down the benefits of facet, helping you understand how it can greatly improve your Rust projects.

facet offers crucial type reflection capabilities for Rust, even within const contexts. A type implementing the Facet trait returns a Shape, giving detailed information about the type. This makes advanced operations possible.

Memory Layout: Understanding how data is organized in memory for optimization.
Definitions: Accessing struct fields and underlying types for better type handling.
Drop Semantics: Knowing how to correctly deallocate memory when it's no longer needed.

Building and Manipulating Types with `Poke`

The Poke type lets you allocate memory (or use existing uninitialized memory) and build up a Facet type piece by piece. Fill the fields step-by-step until you have a fully constructed, valid value. Here's how Poke empowers you:

Incremental Initialization: Set the values of fields one at a time.
Safe Construction: Guarantees a valid state before moving the value, preventing undefined behavior.
Flexibility: Works with both allocating new memory and using pre-allocated, uninitialized memory.

Reading Data with `Peek`

The Peek type provides read-only access to Facet types. The derive macro uses unsynn for compilation speed.

facet is built as a collection of modular crates, each handling a specific aspect of the reflection process. This modularity allows you to pick and choose the functionalities you need:

facet (hub crate): The central point for all things facet.
Separate crates for: trait definitions, core types, derive macro, peek, poke, serializers, deserializers, and pretty printers.

Consult the main facet crate's README to get started and explore all available features.

Facet also provides mechanisms for serializing and deserializing Rust types, extending its utility beyond simple reflection. You can use facet alongside other crates for transforming data into various formats.
