Module middleware 

Shared utilities for token renewal.

Structs

MiddlewareWrapper 🔒

A wrapper that implements [reqwest_middleware::Middleware] by delegating to a MiddlewareExt for token retrieval. We can’t implement [Middleware] directly on MiddlewareExt because [Middleware] is defined in an external crate, so we use this wrapper to bridge between them.

Constants

TOKEN_RENEW_MARGIN_SECONDS 🔒

Traits

MiddlewareExt 🔒

Trait used to share over the token attaching middleware. This is implemented by the token management structs, leaving them responsible for handling token retrieval and renewal logic. The middleware simply calls MiddlewareExt::get_token to get the current token (renewing if necessary) and attaches it to the request.
