Cargo Features

[dependencies]
simple-uuid = { version = "0.5.1", default-features = false, features = ["mac_addr", "hash_sha1", "hash_md5", "rand_num"] }
default = hash_md5, hash_sha1, mac_addr, rand_num

These default features are set whenever simple-uuid is added without default-features = false somewhere in the dependency tree.

mac_addr default = mac_address
hash_sha1 default = sha1
hash_md5 default = md5
rand_num default = rand_core

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.

mac_address mac_addr
rand_core rand_num
md5 hash_md5
sha1 hash_sha1

Enables sha1 ^0.6.0
