Struct bonsaidb_core::keyvalue::Timestamp

pub struct Timestamp {
    pub seconds: u64,
    pub nanos: u32,
}

A timestamp relative to UNIX_EPOCH.

Fields

seconds: u64

The number of whole seconds since UNIX_EPOCH.

nanos: u32

The number of nanoseconds in the timestamp.

Implementations

impl Timestamp

pub const MIN: Self

The minimum representable Timestamp. This is equivalent to UNIX_EPOCH.

pub const MAX: Self

The maximum valid value of Timestamp.

pub fn now() -> Self

Returns the current timestamp according to the OS. Uses SystemTime::now().

Trait Implementations

impl Add<Duration> for Timestamp

type Output = Self

The resulting type after applying the + operator.

fn add(self, rhs: Duration) -> Self::Output

Performs the + operation.

impl Clone for Timestamp

fn clone(&self) -> Timestamp

Returns a copy 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<'de> Deserialize<'de> for Timestamp

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl From<SystemTime> for Timestamp

fn from(time: SystemTime) -> Self

Converts to this type from the input type.

impl From<Timestamp> for Duration

fn from(t: Timestamp) -> Self

Converts to this type from the input type.

impl<'a> Key<'a> for Timestamp

fn from_ord_bytes(bytes: &'a [u8]) -> Result<Self, Self::Error>

Deserialize a sequence of bytes previously encoded with KeyEncoding::as_ord_bytes.

fn first_value() -> Result<Self, NextValueError>

Return the first value in sequence for this type. Not all types implement this.

fn next_value(&self) -> Result<Self, NextValueError>

Return the next value in sequence for this type. Not all types implement this. Instead of wrapping/overflowing, None should be returned.

impl<'a> KeyEncoding<'a, Timestamp> for Timestamp

type Error = IncorrectByteLength

The error type that can be produced by either serialization or deserialization.

const LENGTH: Option<usize>

The size of the key, if constant. If this type doesn’t produce the same number of bytes for each value, this should be None.

fn as_ord_bytes(&'a self) -> Result<Cow<'a, [u8]>, Self::Error>

Convert self into a Cow<[u8]> containing bytes that are able to be compared via memcmp in a way that is comptaible with its own Ord implementation.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<Timestamp> for Timestamp

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

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

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

This method tests for !=.

impl PartialOrd<Timestamp> 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

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

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

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

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

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

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

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

impl Serialize for Timestamp

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl Sub<Timestamp> for Timestamp

type Output = Option<Duration>

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl Copy for Timestamp
