It wraps Cargo to transparently cache build artifacts across runs and machines, with particular emphasis on sharing caches across pull requests and CI workflows\u2014a capability that generic per-key caching cannot provide. The tool downloads the correct Rust toolset for your project (reading from rust-toolchain.toml if present), handles Windows ABI selection automatically, and layers zccache-backed artifact caching on top without requiring separate setup.\n\nThe package is distributed as a Python wheel that acts as a launcher; during installation it downloads the matching soldr binary for your OS and architecture, verifies it against published SHA256 checksums, and exposes the soldr command. It supports Intel and Apple Silicon macOS, Linux (x86_64 and aarch64), Windows (x86_64 and arm64), and integrates with GitHub Actions via a companion setup action. The tool is beta software and actively maintained, with recent releases and no known vulnerabilities.","worth_installing":"Yes, if you run Rust builds in CI or across multiple machines and want to reduce compilation time via cross-PR cache sharing. The active maintenance, permissive license, zero runtime dependencies, and no known vulnerabilities make it low-risk. Install with caution if your project uses non-standard Cargo setups; the fact sheet does not clarify compatibility with all workspace configurations. Pin the version (as the description recommends for beta software) until you validate it in your workflow."},"id":"soldr","links":{"html":"https://skillfed.io/packages/soldr","md":"https://skillfed.io/packages/soldr.md","pypi":"https://pypi.org/project/soldr/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-11","license_spdx":"BSD-3-Clause","license_treatment":"permissive","name":"soldr","python_support":"supports_current","summary":"Instant tools.
