mlir-rs/melior

What it solves

Melior provides a safe and simplified way for Rust developers to interact with MLIR (Multi-Level Intermediate Representation), which is typically accessed via a complex C API. It bridges the gap between the low-level C interface and Rust's ownership and type systems to make building compilers and IR-based tools more ergonomic.

How it works

It acts as a high-level wrapper around the MLIR C API. The library maps MLIR's loose ownership model into Rust's type system, using specific naming conventions for owned objects versus borrowed references and utilizing &T instead of &mut T to manage the intricacies of the underlying C objects.

Who it’s for

Compiler engineers and developers building machine learning frameworks or hardware-specific backends who want to use MLIR within the Rust ecosystem.

Highlights

• Type-Safe API: Aims to provide a complete and safe API for MLIR operations.
• C API Wrapper: Directly wraps the official MLIR C API for full functionality.
• Ownership Management: Implements a sane ownership model to handle MLIR objects in Rust.
• Dialect Support: Includes utilities to register and load available MLIR dialects.
