Struct UUID 

pub struct UUID(/* private fields */);

Is a 128-bit number used to identify information in computer systems.

Implementations

impl UUID

pub fn v3(any: &str, namespace: UUID) -> Layout

Generate a UUID by hashing a namespace identifier and name uses MD5.

pub fn v5(any: &str, namespace: UUID) -> Layout

Generate a UUID by hashing a namespace identifier and name uses SHA1.

impl UUID

pub fn v4() -> Layout

Generate a UUID from truly random numbers.

impl UUID

pub fn v1() -> Layout

Generate a time based and MAC-address UUID. Uses an optimized implementation that caches the MAC address and handles timestamp collisions. The old v1() functionality is preserved for backward compatibility.

pub fn v2(d: Domain) -> Layout

Generate a time based, MAC-address and DCE-security UUID. Preserves the old v2() functionality for backward compatibility.

NOTE: RFC-4122 reserves version-2 for DCE-security UUIDs; but it does not provide any details.

pub fn from_mac(v: Version, mac: [u8; 6]) -> Layout

Generate a time based UUID (version 1|2) with a user defined MAC-address. Optimized to minimize bitwise operations.

impl UUID

pub const NAMESPACE_DNS: Self

UUID namespace for domain name system (DNS).

pub const NAMESPACE_OID: Self

UUID namespace for ISO object identifiers (OIDs).

pub const NAMESPACE_URL: Self

UUID namespace for uniform resource locators (URLs).

pub const NAMESPACE_X500: Self

UUID namespace for X.500 distinguished names (DNs).

Trait Implementations

impl Clone for UUID

fn clone(&self) -> UUID

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UUID

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for UUID

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for UUID

fn eq(&self, other: &UUID) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
