From d6b85ce300e7e62a7e8546f719332ada319afdcb Mon Sep 17 00:00:00 2001 From: parsaba Date: Thu, 3 Jul 2025 00:27:39 +0400 Subject: [PATCH] feat: extract lightweight serialization component from clarity crate MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #6236 Problem: - The clarity crate included the full Clarity VM with heavy dependencies like rusqlite - Downstream crates needed to compile the entire VM just to serialize/deserialize Clarity values - This made it difficult to build lightweight applications that only needed serialization Solution: - Created new `clarity-serialization` crate with minimal dependencies - Extracted core serialization types and traits from the main clarity crate - Maintained full API compatibility for existing code Changes: - Add new `clarity-serialization` crate with lightweight dependencies - Extract Value enum and all supporting types (TupleData, ListData, etc.) - Extract ClaritySerializable/ClarityDeserializable traits and serialization logic - Extract core representations (ClarityName, ContractName, QualifiedContractIdentifier) - Add comprehensive error handling and validation - Update main clarity crate to depend on and re-export from clarity-serialization - Add workspace member for new crate - Include working example demonstrating usage Benefits: - Downstream applications can serialize Clarity values without heavy VM dependencies - Faster compilation for lightweight use cases - Better separation of concerns between serialization and VM logic - Maintains backwards compatibility 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- Cargo.lock | 19 ++ Cargo.toml | 1 + clarity-serialization/Cargo.toml | 43 +++

Serialization + +A lightweight serialization component for Clarity values, extracted from the main Clarity VM to provide core serialization/deserialization functionality without heavy dependencies. + +## Overview + +This crate provides the essential types and functions needed to serialize and deserialize Clarity values, without requiring the full Clarity VM with its database dependencies like rusqlite. + +## Features + +- **Lightweight**: Only includes serialization-related code and minimal dependencies +- **Core Types**: Includes all essential Clarity value types (Int, UInt, Bool, Sequence, Principal, Tuple, Optional, Response, CallableContract) +- **Serialization Traits**: Provides `ClaritySerializable` and `ClarityDeserializable` traits for custom types +- **Multiple Formats**: Supports both binary and hex string serialization +- **Type Safety**: Maintains the same type safety guarantees as the full Clarity crate + +## Usage + +```rust +use clarity_serialization::{Value, ClaritySerializable}; + +// Create a value +let value = Value::UInt(42); + +// Serialize to bytes +let bytes = value.serialize_to_vec()?; + +// Serialize to hex string +let hex = value.serialize_to_hex()?; + +// Deserialize from bytes +let restored = Value::deserialize_from_slice(&bytes)?; + +// Deserialize from hex +let restored = Value::deserialize_from_hex(&hex)?; + +assert_eq!(value, restored); +``` + +## Custom Serialization + +For custom types, use the `clarity_serializable!` macro: + +```rust +use clarity_serialization::{clarity_serializable, ClaritySerializable}; + +#[derive(Serialize, Deserialize)] +struct MyType { + data: String, +} + +clarity_serializable!(MyType); + +let my_value = MyType { data: "test".to_string() }; +let serialized = my_value.serialize(); +``` + +## Dependencies + +This crate has minimal dependencies compared to the full Clarity crate: +- `serde` and `serde_json` for JSON serialization +- `stacks_common` for basic utilities (without rusqlite features) +- Standard library components + +## Motivation + +The original `clarity` crate includes the full Clarity VM with heavy dependencies like rusqlite, making it difficult for downstream applications that only need serialization functionality. This lightweight crate solves that by providing just the core serialization components. + +## Compatibility + +This crate maintains full compatibility with values serialized by the main Clarity crate, ensuring seamless interoperability. \ No newline at end of file diff --git a/clarity-serialization/examples/basic_usage.rs b/clarity-serialization/examples/basic_usage.rs new file mode 100644 index 0000000000..325b0adfca --- /dev/null +++ b/clarity-serialization/examples/basic_usage.rs @@ -0,0 +1,83 @@ +// Example demonstrating basic usage of clarity-serialization + +use clarity_serialization::{ + Value, ClaritySerializable, ClarityDeserializable, + SerializationError, to_hex, from_hex +}; + +fn main() -> Result<(), Box> { + println!("=== Clarity Serialization Example ===\n"); + + // Create some basic values + let uint_value = Value::UInt(42); + let bool_value = Value::Bool(true); + let none_value = Value::none(); + + println!("1.
