Struct Timestamp 

#[repr(transparent)]
pub struct Timestamp(pub u64);

Logical timestamp for MVCC versioning.

Timestamps are monotonically increasing values used to order events and determine version visibility.

Tuple Fields

0: u64

Performs the += operation.

impl Clone for Timestamp

fn clone(&self) -> Timestamp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Timestamp

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

Formats the value using the given formatter.

impl Default for Timestamp

fn default() -> Timestamp

Returns the “default value” for a type.

impl Display for Timestamp

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

Formats the value using the given formatter.

impl From<Timestamp> for u64

fn from(ts: Timestamp) -> Self

Converts to this type from the input type.

impl From<u64> for Timestamp

fn from(ts: u64) -> Self

Converts to this type from the input type.

impl Hash for Timestamp

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 Timestamp

fn cmp(&self, other: &Timestamp) -> 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.

impl PartialEq for Timestamp

fn eq(&self, other: &Timestamp) -> 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.

impl PartialOrd for Timestamp

fn partial_cmp(&self, other: &Timestamp) -> 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.

type Output = Timestamp

The resulting type after applying the - operator.

fn sub(self, rhs: u64) -> Timestamp

Performs the - operation.

impl Sub for Timestamp

type Output = Timestamp

The resulting type after applying the - operator.

fn sub(self, rhs: Timestamp) -> Timestamp

Performs the - operation.

impl SubAssign<u64> for Timestamp

fn sub_assign(&mut self, rhs: u64)

Performs the -= operation.

impl Copy for Timestamp

impl Eq for Timestamp
