Crate uuid_rs

uuid-rs implements Universally Unique IDentifiers (UUIDs) according to RFC 4122. UUIDs are 128-bit numbers that can be used to uniquely identify resources in distributed systems. Multiple UUID versions are supported, including timestamp-based (v1), DCE Security (v2), MD5 hash-based (v3), random (v4) and SHA-1 hash-based (v5) variants.

Macros

v1

Creates a lower String for UUID version-1.

v2

Creates a lower String for UUID version-2.

v3

Creates a lower String for UUID version-3.

v4

Creates a lower String for UUID version-4.

v5

Creates a lower String for UUID version-5.

Structs

ClockSeq

The clock sequence is used to help avoid duplicates that could arise when the clock is set backwards in time or if the node ID changes. According to RFC 4122, it is initialized with a random value when the UUID generator starts up.

Layout

The UUID format is 16 octets.

Node

The clock sequence is used to help avoid duplicates that could arise when the clock is set backwards in time or if the node ID changes.

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

Domain

Domain is security-domain-relative name.

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.
