Struct BearerTokenAuthorizer

pub struct BearerTokenAuthorizer { /* private fields */ }

Create a simple Authorizer that attaches a given token to any request a client sends. The token is attached with the Bearer auth-scheme.

Tonic

If the tonic feature is enabled, tonic::service::Interceptor is implemented for BearerTokenAuthorizer. The interceptor does not insert the access token if the intercepted call already has an Authorization header.

Implementations

impl BearerTokenAuthorizer

pub fn new(token: &str) -> Result<Self>

Create a new interceptor with the given access token. Pass only the token, without the Bearer prefix.

Errors

Fails if “Bearer {token}” is not a valid ASCII string.
