With Cargo installed, the following command will build and install cargo-user from crates.io automatically:
bash
cargo install cargo-user
As long as $HOME/.cargo/bin/ is included in $PATH, the subcommand should be available immediately.
Assuming you have already run cargo login, you should first run cargo user save to save your credentials as a profile. You can then clear your credentials with cargo logout or cargo user clear, log in again with different credentials, and save those too.
```bash cargo user save first
cargo user clear
cargo login
cargo user save second
```
You can then invoke cargo user current to print the name of the currently loaded profile, cargo user list to view all available profiles, and cargo user load to switch to another.
```bash cargo user list
cargo user current
cargo user load first
cargo user current
```
A complete list of capabilities can be accessed with cargo help user or cargo user --help.
User credentials for publishing to crates.io are saved in $CARGO_HOME/credentials. This plugin saves a copy of that file, with a user-specified name, as a credentials "profile" in $XDG_CONFIG_HOME/cargo-user/profiles/.
For example, a profile named "third", saved with cargo user save third, would be saved at $XDG_CONFIG_HOME/cargo-user/profiles/credentials-third. When that profile is later loaded with cargo user load third, that file is copied back to $CARGO_HOME/credentials, and is immediately accessible to be read by cargo publish.
The exact path to the saved profile directory, or to a specific profile, can be printed with cargo user find.
