Struct Uuid 

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

RFC 9562; ordered by bytes so version 7 ids sort in creation order.

pub const fn from_u128(value: u128) -> Self

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

pub fn push_to(self, out: &mut String)

pub fn now_v7() -> Result<Self, RandomnessUnavailable>

pub fn new_v4() -> Result<Self, RandomnessUnavailable>

Trait Implementations

impl Cast for Uuid

const COLUMNS: &'static [ColumnSpec]

fn encode(&self, out: &mut Vec<SqlValue>)

fn decode(row: &mut dyn ColumnReader) -> Result<Self>

const NULLABLE: bool = false

const SENSITIVE: bool = false

A field holding it is never filtered, sorted, listed or searched, as #[sensitive] ones.

const MOVES: Option<Moves<Self>> = None

Set for a value moving between listed states; a save of any other value skips the check.

const HOLDS_STATES: bool

Set when a state anywhere in the value is checked on save, as a field’s of several.

fn refuse_unlisted_move( field: &str, stored: &Self, current: &Self, ) -> Result<()>

impl Clone for Uuid

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Uuid

impl Debug for Uuid

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Uuid

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Uuid

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

Formats the value using the given formatter.

impl Eq for Uuid

impl FromStr for Uuid

type Err = ParseUuidError

The associated error which can be returned from parsing.

fn from_str(text: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Uuid

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Uuid

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

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

Restrict a value to a certain range.

impl PartialEq for Uuid

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Uuid

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Uuid

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>
