+//! This crate provides some of the core functionality or interfaces for the other Argus
+//! components. Mainly, the crate provides:
+//!
+//! 1. Expression tree nodes for defining temporal logic specifications (see [`expr`]).
+//! 2. Different signal types for generating traces of data (see [`signals`]).
+//! 3. A list of possible errors any component in Argus can generate (see
+//!    [`enum@Error`]).
