Add Cargo package registry (go-gitea#21888)
This PR implements a [Cargo registry](https://doc.rust-lang.org/cargo/) to manage Rust packages. This package type was a little bit more complicated because Cargo needs an additional Git repository to store its package index. Screenshots:    --------- Co-authored-by: Lunny Xiao <[email protected]>

| # Cargo Packages Repository | ||
|
|
||
| Publish [Cargo](https://doc.rust-lang.org/stable/cargo/) packages for your user or organization. | ||
|
|
||
| **Table of Contents** | ||
|
|
||
| {{< toc >}} | ||
|
|
||
| ## Requirements | ||
|
|
||
| To work with the Cargo package registry, you need [Rust and Cargo](https://www.rust-lang.org/tools/install). | ||
|
|
||
| Cargo stores informations 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 Gitea 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 Gitea instance domain was changed. | ||
|
|
||
| If the case arises where the packages stored in Gitea 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 = "gitea" | ||
| [registries.gitea] | ||
| index = "https://gitea.example.com/{owner}/_cargo-index.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.gitea] | ||
| token = "Bearer {token}" | ||
| ``` | ||
|
|
||
| | Parameter | Description | | ||
| | --------- | ----------- | | ||
| | `token` | Your [personal access token]({{< relref "doc/developers/api-usage.en-us.md#authentication" >}}) | | ||
|
|
||
| ## 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 | ||
| ``` |
