Cargo Features

StringMatch has no features set by default.

[dependencies]
stringmatch = { version = "0.4.0", features = ["serde_derive"] }
serde_derive = serde

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.
