Gust

An extremely fast Swift package manager, written in Rust.

Benchmarked on Vapor (19 deps, 28 transitive) — up to 265x faster

Highlights

• 4-265x faster than SwiftPM for common operations
• Parallel dependency fetching with concurrent git clones
• Content-addressable cache with hard links (pnpm-style)
• Binary artifact caching for near-instant rebuilds
• Works with existing Package.swift files or simpler Gust.toml
