Struct uuid_rs::UUID

pub struct UUID(_);

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

Implementations

impl UUID

pub fn v1() -> Layout

Generate a time-based and MAC-address UUID.

pub fn v2(d: Domain) -> Layout

Generate a time-based, MAC address and DCE security version UUID.

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

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 Eq for UUID

impl LowerHex for UUID

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

impl Ord for UUID

fn cmp(&self, other: &UUID) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<UUID> for UUID

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<UUID> for UUID

fn partial_cmp(&self, other: &UUID) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
