Porting Turborepo From Go To Rust
summary
Turborepo moves from Go to Rust incrementally: start with a Rust shim and CI parser, port hot dependencies via a Rust-Go-Rust sandwich, then build a full Rust execution pipeline. The team rewrites ~70,000 lines in 15 months, cross-compiles for six targets using Zig for C toolchains, and uses clap, protobuf/CapnProto, napi, swc, biome and pretty-print libraries. The result ships as an all-Rust 1.11 release, reduces issues, yields modest perf gains, and adds better errors and a new UI.
