Cargo Features

matrixcompare has no features set by default.

[dependencies]
matrixcompare = { version = "0.3.0", features = ["proptest-support"] }
proptest-support = proptest

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
