cargo-vendor

cargo vendor [options] [path]

cargo vendor downloads and copies all crates.io and git dependencies into a local directory (default: `vendor/`). It outputs the Cargo configuration needed to redirect dependency resolution to the vendored sources.This is primarily used for offline builds, air-gapped environments, and reproducible build systems where network access during compilation is not available or not desired. The vendored sources are read-only; to modify a vendored crate, use the `[patch]` section in Cargo.toml instead of editing files directly in the vendor directory.

.cargo/config.toml

Source replacement settings that redirect dependency resolution to the vendored directory. The output of `cargo vendor` provides the exact configuration to add.

After vendoring:

$ cargo build --offline

Vendored sources are read-only. Use [patch] for modifications. Resolution may differ from online mode. Run cargo fetch first for complete dependency download.
