Crate simple_uuid

This crate defines a uniform resource name namespace for UUIDs (Universally Unique IDentifier), also known as GUIDs (Globally Unique Identifier). A UUID is 128 bits long, and can guarantee uniqueness across space and time.

[dependencies]
simple-uuid = { version = "*", features = ["rand_num"] }

use simple_uuid::v4;
println!("{}", v4!());

Macros

v1	mac_addr UUID version-1
v3	hash_md5 UUID version-3
v4	rand_num UUID version-4
v5	hash_sha1 UUID version-5

Structs

ClockSeq	Used to avoid duplicates that could arise when the clock is set backwards in time.
Layout	The UUID format is 16 octets.
Node	Node field consists of an IEEE 802 MAC address, usually the host address
TimeStamp	Represented by Coordinated Universal Time (UTC) as a count of 100-ns intervals from the system-time.
UUID	Is a 128-bit number used to identify information in computer systems.

Enums

Variant	Variant is a type field determines the layout of the UUID.
Version	Version represents the type of UUID, and is in the most significant 4 bits of the Timestamp.

Constants

UTC_EPOCH

Is 100-ns ticks between UNIX and UTC epochs.
