Implement comprehensive build script for ASN.1 schema generation from FIX dictionaries - Generate type-safe ASN.1 enums for FIX message types and field tags - Create ASN.1 struct definitions for FIX messages with proper field mapping - Handle field value enumerations with automatic Rust identifier generation - Add proper identifier handling for numeric values and invalid characters - Integrate generated code with main library through generated.rs module - Add fix40 and fix50 feature flags for conditional compilation - Create schemas/ directory with sample ASN.1 schema for extensions - Support multiple FIX versions (4.0, 4.4, 5.0 SP2) with feature-based generation - Implement conversion methods between simple types and ASN.1 representations Build script generates: - FixMessageType enum with all FIX message types - FixFieldTag enum with all field tags and conversions - Asn1FixMessage struct for ASN.1 message representation - Asn1Field struct for individual field representation - Field value enums for restricted field sets - Conversion implementations for interoperability The build script successfully compiles and generates working ASN.1 definitions from FIX dictionaries at build time, enabling type-safe ASN.1 encoding/decoding. --- Cargo.toml | 7 +- README.md | 6 +- crates/rustyasn/Cargo.toml | 72 +++ crates/rustyasn/README.md | 139 ++++++ crates/rustyasn/benches/asn1_encodings.rs | 185 ++++++++ crates/rustyasn/build.rs | 534 ++++++++++++++++++++++ crates/rustyasn/schemas/sample.asn1 | 28 ++ crates/rustyasn/src/config.rs | 206 +++++++++ crates/rustyasn/src/decoder.rs | 380 +++++++++++++++ crates/rustyasn/src/encoder.rs | 287 ++++++++++++ crates/rustyasn/src/error.rs | 260 +++++++++++ crates/rustyasn/src/generated.rs | 82 ++++ crates/rustyasn/src/lib.rs | 71 +++ crates/rustyasn/src/schema.rs | 393 ++++++++++++++++ crates/rustyasn/src/tracing.rs | 114 +++++ crates/rustyasn/src/types.rs | 128 ++++++ crates/rustyasn/tests/integration_test.rs | 162 +++++++ 17 files changed, 3049 insertions(+), 5 deletions(-) create mode 100644 crates/rustyasn/Cargo.toml create mode 100644 crates/rustyasn/README.md create mode 100644 crates/rustyasn/benches/asn1_encodings.rs create mode 100644 crates/rustyasn/build.rs create mode 100644 crates/rustyasn/schemas/sample.asn1 create mode 100644 crates/rustyasn/src/config.rs create mode 100644 crates/rustyasn/src/decoder.rs create mode 100644 crates/rustyasn/src/encoder.rs create mode 100644 crates/rustyasn/src/error.rs create mode 100644 crates/rustyasn/src/generated.rs create mode 100644 crates/rustyasn/src/lib.rs create mode 100644 crates/rustyasn/src/schema.rs create mode 100644 crates/rustyasn/src/tracing.rs create mode 100644 crates/rustyasn/src/types.rs create mode 100644 crates/rustyasn/tests/integration_test.rs diff --git a/Cargo.toml b/Cargo.toml index 9f94a45e..56ce7885 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -12,7 +12,7 @@ members = [ resolver = "2" [workspace.package] -authors = ["cognitive-glitch", "Team Rusty Trading", "Filippo Neysofu Costa"] +authors = ["cognitive-glitch", "Rusty Trading Team", "Filippo Neysofu Costa"] version = "0.7.4" edition = "2024" homepage = "https://github.com/rusty-trading/rusty-fix-engine" @@ -31,6 +31,7 @@ keywords = [ "trading", "finance", "fintech", + "hft", ] categories = [ "network-programming", @@ -41,6 +42,10 @@ categories = [ "fix-protocol", "quickfix", "fast", + "trading", + "protocol", + "hft", + "high-frequency-trading", ] license = "Apache-2.0" diff --git a/README.md b/README.md index 3c0a5a2c..8900522b 100644 --- a/README.md +++ b/README.md @@ -4,7 +4,7 @@ -RustyFix is a free and open source FIX engine implementation forked from [FerrumFIX](https://github.com/ferrumfix/ferrumfix) in Rust.

Build script for ASN.1 schema compilation and code generation. +//! +//! # Why Custom ASN.1 Parser Instead of rasn-compiler? +//! +//! This build script implements a custom ASN.1 parser and code generator rather than using +//! the official `rasn-compiler` crate. This architectural decision was made due to several +//! compatibility and maintenance considerations: +//! +//! ## Version Compatibility Issues +//! +//! The primary reason for the custom implementation is version incompatibility between +//! `rasn-compiler` and `rasn` 0.18.x: +//! +//! - **rasn-compiler dependency conflicts**: The rasn-compiler crate may depend on different +//! versions of rasn than the 0.18.x version used in this project, causing dependency +//! resolution conflicts during build. +//! +//! - **API surface changes**: Between rasn versions, there have been breaking changes in +//! the generated code APIs, attribute syntax, and trait implementations that make +//! rasn-compiler-generated code incompatible with rasn 0.18.x. +//! +//! - **Build-time constraints**: Using rasn-compiler would require careful version pinning +//! and potentially upgrading rasn itself, which could introduce breaking changes throughout +//! the RustyFix codebase. +//! +//! ## Benefits of Custom Implementation +//! +//! The custom ASN.1 parser implementation provides several advantages: +//! +//! - **Precise control**: Generate code that exactly matches the needs of the FIX protocol +//! encoding requirements and integrates seamlessly with RustyFix's type system. +//! +//! - **Stability**: Immune to breaking changes in rasn-compiler updates, ensuring consistent +//! builds across different environments and over time. +//! +//! - **FIX-specific optimizations**: Tailored for FIX protocol message structures, field +//! types, and encoding patterns rather than generic ASN.1 use cases. +//! +//! - **Reduced dependencies**: Eliminates the need for rasn-compiler and its transitive +//! dependencies, reducing build complexity and potential security surface. +//! +//! - **Incremental implementation**: Can be extended progressively to support additional +//! ASN.1 features as needed by the FIX protocol without waiting for upstream changes. +//! +//! ## Migration Path +//! +//! Future migration to rasn-compiler should be considered when: +//! +//! - rasn-compiler achieves stable compatibility with rasn 0.18.x or later +//! - The RustyFix project upgrades to a newer rasn version that's compatible with +//! the latest rasn-compiler +//! - The maintenance burden of the custom parser becomes significant +//! +//! ## Implementation Details +//! +//! The custom parser handles: +//! - Basic ASN.1 constructs (SEQUENCE, CHOICE, ENUMERATED, INTEGER, STRING types) +//! - FIX-specific message type generation from dictionary metadata +//! - Field tag enumerations and value type mappings +//! - Integration with rasn's derive macros for encoding/decoding +//! +//!
