Mercury - Rust to PureScript Type Generator

Mercury automatically generates PureScript type definitions and Argonaut JSON codecs from Rust types annotated with #[mercury].

Overview

This library provides the core functionality for:

• Scanning Rust source files for #[mercury] annotations
• Parsing Rust type definitions using the syn crate
• Analyzing and mapping Rust types to PureScript equivalents
• Generating PureScript type definitions and JSON codecs
• Writing organized multi-module output

Example

use mercury::generate;

// Generate PureScript from annotated Rust types
let result = generate(".")?;
println!("Generated {} types in {} modules", result.type_count, result.module_count);

Re-exports

pub use error::MercuryError;

pub use error::Result;
