//! Tests for `matrixcompare` integration.

//!
|
|
//! The `matrixcompare` crate itself is responsible for testing the actual comparison.
|
|
//! The tests here only check that the necessary trait implementations are correctly implemented,
|
|
//! in addition to some sanity checks with example input.
