zerus

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

Requirements

Currently, this relies on nightly sparse-registry

Build zerus

Either build from published source in crates.io.

$ cargo install zerus

Or download from github releases.

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:

$ 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"
