cargo-fetch
Download dependencies for offline builds
TLDR
Fetch all dependencies
$ cargo fetch
Fetch for specific target$ cargo fetch --target [x86_64-unknown-linux-gnu]
Fetch with locked versions$ cargo fetch --locked
Fetch offline (from cache)$ cargo fetch --offline
SYNOPSIS
cargo fetch [options]
DESCRIPTION
cargo fetch downloads all dependencies from the network and stores them locally. If Cargo.lock exists, fetches exact versions specified. Otherwise, generates the lock file first.Useful for preparing to work offline with the --offline flag.
PARAMETERS
--target triple
Fetch for specified target architecture (can be repeated)--locked
Assert same dependencies as original Cargo.lock--offline
Use only locally cached crates--frozen
Equivalent to --locked and --offline--manifest-path path
Path to Cargo.toml-v, --verbose
Verbose output-q, --quiet
Suppress log messages
BEHAVIOR
Without --target, fetches all target dependencies. Git dependencies are cloned with submodules. Registry crates are downloaded to cargo cache.
INSTALL
sudo apt install cargo
sudo dnf install cargo
sudo apk add cargo
sudo zypper install cargo
nix profile install nixpkgs#cargo
CAVEATS
Subsequent cargo commands can run offline after fetch unless lock file changes. Network access required unless using --offline with cached dependencies.
