Library to Provide a User Authentication and privilege Token Checks. It requires the Axum_Session library. This library will help by making it so User ID or authorizations are not stored on the Client side but rather on the Server side. The Authorization is linked by the Clients Serverside Session ID which is stored on the Client side. Formally known as Axum Sessions Auth
axum_session
for data management serverside.If you need help with this library or have suggestions please go to our Discord Group
Sessions Authentication uses tokio
runtime and ['axum_session'];
# Cargo.toml
[dependencies]
# Postgres + rustls
axum_session_auth = { version = "0.14.0" }
axum_session_sqlx = { version = "0.3.0" }
Features | Description |
---|---|
advanced |
Enable functions allowing more direct control over the sessions. |
rest_mode |
Disables Cookie Handlering In place of Header only usage for Rest API Requests and Responses. |
key-store |
Enabled the optional key storage. Will increase ram usage based on Fastbloom settings. |
