Cargo

Avrea caches crates from crates.io so that cargo build and cargo fetch resolve dependencies from colocated cache on repeat runs.

On Avrea runners

Cargo is pre-configured via ~/.cargo/config.toml:

~/.cargo/config.toml

[registries.cache]
index = "sparse+https://avrea-host:8443/cargo/"

[source.crates-io]
replace-with = "cache"

Your workflow needs no changes:

workflow.yml

jobs:
  build:
    runs-on: avrea-ubuntu-latest
    steps:
      - uses: actions/checkout@v6
      - run: cargo build --release

Manual setup

Create or append to ~/.cargo/config.toml:

~/.cargo/config.toml

[registries.cache]
index = "sparse+https://avrea-host:8443/cargo/"

[source.crates-io]
replace-with = "cache"
