# auth0_rs

Simple Auth0 access token validation package.

## Usage

Use `Auth0::new(JWKS_URL)` to initialize your an `Auth0` instance.
Then pass in your access token to the function `auth0.validate_token(YOUR_TOKEN)`.
This function returns a `serde_json::Value` type object as `Claims` if the validation is successful;
otherwise returns an error.

Example:
```rust
let keys = r#"
{
    "keys":[
        {
          "kty": "RSA",
          "n": "nzyis1ZjfNB0bBgKFMSvvkTtwlvBsaJq7S5wA-kzeVOVpVWwkWdVha4s38XM_pa_yr47av7-z3VTmvDRyAHcaT92whREFpLv9cj5lTeJSibyr_Mrm_YtjCZVWgaOYIhwrXwKLqPr_11inWsAkfIytvHWTxZYEcXLgAXFuUuaS3uF9gEiNQwzGTU1v0FqkqTBr4B8nW3HCN47XUu0t8Y0e-lf4s4OxQawWD79J9_5d3Ry0vbV3Am1FtGJiJvOwRsIfVChDpYStTcHTCMqtvWbV6L11BWkpzGXSW4Hv43qa-GSYOD2QU68Mb59oSk2OB-BtOLpJofmbGEGgvmwyCI9Mw",
