# comnum-core
[](https://crates.io/crates/comnum-core)
[](https://docs.rs/comnum-core)
Part of [comnum](https://github.com/com-rs/comnum), link-level simulation of digital communication systems,
wireless and optical. Layer 0 (the foundation) of the workspace, whose dependencies
point downward only ([architecture](https://github.com/com-rs/comnum/blob/main/docs/ARCHITECTURE.md)).
The vocabulary every block of comnum shares: the multi-stream containers (`Bits`, `Llr`, `Symbols`, `Signal`, `DualPol`), the verb traits (`Map`, `Demap`, `Propagate`, `Impair`, …), the unit newtypes (`Db`, `EbN0`, `EsN0`, `Hertz`), the seeded generator `SimRng` (xoshiro256\*\*, one stream per trial) and the error type.
Most users depend on the facade [`comnum`](https://crates.io/crates/comnum), which
re-exports this crate as `comnum::core`. The API is documented on
[docs.rs/comnum-core](https://docs.rs/comnum-core), with the formula that every item implements.
