# cargo-credential
This package is a library to assist writing a Cargo credential helper, which
provides an interface to store tokens for authorizing access to a registry
such as https://crates.io/.
Documentation about credential processes may be found at
https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#credential-process
Example implementations may be found at
https://github.com/rust-lang/cargo/tree/master/credential
## Usage
Create a Cargo project with this as a dependency:
```toml
# Add this to your Cargo.toml:
[dependencies]
cargo-credential = "0.3"
```
And then include a `main.rs` binary which implements the `Credential` trait, and calls
the `main` function which will call the appropriate method of the trait:
```rust
// src/main.rs
use cargo_credential::{Credential, Error};
struct MyCredential;
impl Credential for MyCredential {
/// implement trait methods here...
}
fn main() {
cargo_credential::main(MyCredential);
}
```
