Cargo Features

[dependencies]
chksum-hash-sha2 = { version = "0.0.1", default-features = false, features = ["224", "256", "384", "512"] }
default = 224, 256, 384, 512

These default features are set whenever chksum-hash-sha2 is added without default-features = false somewhere in the dependency tree.

224 default = chksum-hash-sha2-224
256 default = chksum-hash-sha2-256
384 default = chksum-hash-sha2-384
512 default = chksum-hash-sha2-512

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.
