Cargo Features

simid has no features set by default.

[dependencies]
simid = { version = "0.1.0", features = ["mac", "random", "hash_sha1", "hash_md5"] }
mac = mac_address, rand
random = rand
hash_sha1 = sha1
hash_md5 = md5

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.

rand mac? random?

Enables rand ^0.7.3
