Struct tarantool::uuid::Uuid

pub struct Uuid { /* private fields */ }

Implementations

impl Uuid

pub fn random() -> Self

pub fn from_inner(inner: Uuid) -> Self

pub fn into_inner(self) -> Uuid

pub fn from_bytes(bytes: [u8; 16]) -> Self

Convert an array of bytes in the big endian order into a Uuid.

pub fn try_from_slice(bytes: &[u8]) -> Option<Self>

Convert a slice of bytes in the big endian order into a Uuid. Return None if there’s not enough bytes in the slice.

pub fn from_tt_uuid(tt: tt_uuid) -> Self

Convert the tarantool native (little endian) uuid representation into a Uuid.

pub fn to_tt_uuid(&self) -> tt_uuid

Return an array of bytes in tarantool native (little endian) format

pub fn as_bytes(&self) -> &[u8; 16]

Return an array of bytes in the big endian order

pub fn nil() -> Self

The ‘nil UUID’.

The nil UUID is special form of UUID that is specified to have all 128 bits set to zero, as defined in IETF RFC 4122 Section 4.1.7.

Examples

Basic usage:

use uuid::Uuid;

let uuid = Uuid::nil();

assert_eq!(
    uuid.to_hyphenated().to_string(),
    "00000000-0000-0000-0000-000000000000"
);

pub fn is_nil(&self) -> bool

Tests if the UUID is nil.

pub fn parse_str(input: &str) -> Result<Self, Error>

Parses a Uuid from a string of hexadecimal digits with optional hyphens.

Any of the formats generated by this module (simple, hyphenated, urn) are supported by this parsing function.

pub const fn to_hyphenated(self) -> Hyphenated

Get a Hyphenated formatter.

pub const fn to_hyphenated_ref(&self) -> HyphenatedRef<'_>

Get a borrowed HyphenatedRef formatter.

pub const fn to_simple(self) -> Simple

Get a Simple formatter.

pub const fn to_simple_ref(&self) -> SimpleRef<'_>

Get a borrowed SimpleRef formatter.

pub const fn to_urn(self) -> Urn

Get a Urn formatter.

pub const fn to_urn_ref(&self) -> UrnRef<'_>

Get a borrowed UrnRef formatter.
