Rust Glancer is an early-stage alternative Rust LSP designed for low memory usage, targeting under 100MB and offering immediate index persistence across editor restarts. Benchmarks show it outperforms rust-analyzer on older hardware like an 8GB MacBook Pro M1, though the project is still missing significant functionality and has known bugs.
Background
rust-analyzer is the dominant Rust language server but is known for high memory consumption, which can be problematic on resource-constrained machines. This project emerged as a lightweight alternative targeting older or lower-RAM systems.
