//! This library consists of all of the things fif needs to run. It only exists as a library to separate code, and to
|
|
//! make documentation and testing a bit easier. I don't recommend using this as a library for your crate, as it may
|
|
//! have breaking changes without incrementing the major version - it's really only meant to be a place for fif's
|
|
//! internals to live.
|
|
//!
|
|
//! You can view [fif's README](https://gitlab.com/Lynnesbian/fif/-/blob/master/README.md#fif) to learn more.
