// dead rust-lang/rustfmt/pull/5394 :(
#![feature(
    decl_macro,
    duration_constructors,
    never_type,
    once_cell_try,
    seek_stream_len
)]
#![allow(clippy::future_not_send)] // will get to fix these later

//! # About, Licensing and More
//!
//! Check the README.md for entry-level documentation.
//!
//! # Where is my documentation?
//!
//! For ease of development and centralized **corrent** information, this codebase will serve both
//! as project documentation AND documentation for the behavior of the OpenID Connect server.
//!
//! Might be hard to figure out how the program behaves based on the code, but I will try to put
//! behavior parameters in [`consts`], so that might be a good starting point to know some stuff
//! (e.g. profile profile picture search path).
//!
//! Checking out [`conf`] might be useful too to know what could've been configured by server
//! administrators and less likely but maybe there can also be certain parameters in [`args`].
//!
//! I will try to keep those 3 modules as documented as possible, please feel free to open any
//! issues/PRs regarding information in there.
