Publish [Cargo](https://doc.rust-lang.org/stable/cargo/) packages for your user or organization.
|
|
|
|
## Requirements
|
|
|
|
To work with the Cargo package registry, you need [Rust and Cargo](https://www.rust-lang.org/tools/install).
|
|
|
|
Cargo stores information about the available packages in a package index stored in a git repository.
|
|
This repository is needed to work with the registry.
|
|
The following section describes how to create it.
|
|
|
|
## Index Repository
|
|
|
|
Cargo stores informations about the available packages in a package index stored in a git repository.
|
|
In Forgejo this repository has the special name `_cargo-index`.
|
|
After a package was uploaded, its metadata is automatically written to the index.
|
|
The content of this repository should not be manually modified.
|
|
|
|
The user or organization package settings page allows to create the index repository along with the configuration file.
|
|
If needed this action will rewrite the configuration file.
|
|
This can be useful if for example the Forgejo instance domain was changed.
|
|
|
|
If the case arises where the packages stored in Forgejo and the information in the index repository are out of sync, the settings page allows to rebuild the index repository.
|
|
This action iterates all packages in the registry and writes their information to the index.
|
|
If there are lot of packages this process may take some time.
|
|
|
|
## Configuring the package registry
|
|
|
|
To register the package registry the Cargo configuration must be updated.
|
|
Add the following text to the configuration file located in the current users home directory (for example `~/.cargo/config.toml`):
|
|
|
|
```
|
|
[registry]
|
|
default = "forgejo"
|
|
|
|
[registries.forgejo]
|
|
index = "sparse+https://forgejo.example.com/api/packages/{owner}/cargo/" # Sparse index
|
|
# index = "https://forgejo.example.com/{owner}/_cargo-index.git" # Git
|
|
|
|
# [net]
|
|
# git-fetch-with-cli = true
|
|
```
|
|
|
|
| Parameter | Description |
|
|
| --------- | ------------------------- |
|
|
| `owner` | The owner of the package. |
|
|
|
|
If the registry is private or you want to publish new packages, you have to configure your credentials.
|
|
Add the credentials section to the credentials file located in the current users home directory (for example `~/.cargo/credentials.toml`):
|
|
|
|
```
|
|
[registries.forgejo]
|
|
token = "Bearer {token}"
|
|
```
|
|
|
|
| Parameter | Description |
|
|
| --------- | ------------------------------------------------------------- |
|
|
| `token` | Your [personal access token](../../api-usage/#authentication) |
|
|
|
|
## Git vs Sparse
|
|
|
|
Currently, cargo supports two ways for fetching crates in a registry: Git index & sparse index.
|
|
Sparse index is the newest method and offers better performance when updating crates compared to git.
|
|
Since Rust 1.68, sparse is the default method for crates.io.
|
|
|
|
## Publish a package
|
|
|
|
Publish a package by running the following command in your project:
|
|
|
|
```shell
|
|
cargo publish
|
|
```
|
|
|
|
You cannot publish a package if a package of the same name and version already exists. You must delete the existing package first.
|
|
|
|
## Install a package
|
|
|
|
To install a package from the package registry, execute the following command:
|
|
|
|
```shell
|
|
cargo add {package_name}
|
|
```
|
|
|
|
| Parameter | Description |
|
|
| -------------- | ----------------- |
|
|
| `package_name` | The package name. |
|
|
|
|
## Supported commands
|
|
|
|
```
|
|
cargo publish
|
|
cargo add
|
|
cargo install
|
|
cargo yank
|
|
cargo unyank
|
|
cargo search
|
|
```
