Summary

Types

endpoint/0

Functions

clear()

Drop all cached tokens. Useful for tests.

handle_call(_, From, Tab)
handle_cast(_, Tab)
init(_)
put(Endpoint, Token)

Store a token for the given endpoint. Overwrites any previous entry for the same endpoint; when the cache is at its size limit, the oldest entry is dropped.

start_link()
take(Endpoint)

Atomically return and remove a cached token for the endpoint, or empty if none is cached. Returning the token consumes it — per RFC 9000 §8.1.3 each NEW_TOKEN is meant to be used at most once.
