zerus

Lightweight binary to download only project required crates for offline crates.io mirror

Requirements

Currently, this relies on nightly sparse-registry

Setup

Create vendor folder with all project dependencies: $ cargo vendor

Run the following command to run this project, pointing to the vendor directory made in the previous step: $ cargo r --release --bin zerus -- vendor offline-mirror

Now clone the crates.io-index: $ cd offline-mirror $ git clone https://github.com/rust-lang/crates.io-index

Serve mirror

Use miniserve.

Build with mirror

For building the project that you ran cargo vendor, add the following to a .cargo/config file(replacing IP with your ip). ``` [unstable] sparse-registry = true

[source.zerus] registry = "sparse+http://[IP]/crates.io-index/"

[source.crates-io] replace-with = "zerus" ```
