sericom_core/
lib.rs

1//! `sericom-core` is the underlying library for [`sericom`](https://crates.io/crates/sericom)
2//!
3//! As it sits right now, this library is largely meant to be solely used by `sericom`
4//! directly. Therefore, it is not intended to be used within other projects/crates.
5//!
6//! If other projects develop a need to use this library within their projects, please
7//! create an [issue](https://github.com/tkatter/sericom) so I can become aware and work
8//! towards making `sericom-core` a generalized/compatible library that is better suited
9//! for use among other crates.
