Struct sqlx::types::uuid::timestamp::Timestamp

pub struct Timestamp { /* private fields */ }

A timestamp that can be encoded into a UUID.

This type abstracts the specific encoding, so versions 1, 6, and 7 UUIDs can both be supported through the same type, even though they have a different representation of a timestamp.

Implementations

impl Timestamp

pub fn now(context: impl ClockSequence<Output = u16>) -> Timestamp

Get a timestamp representing the current system time.

This method defers to the standard library’s SystemTime type.

Panics

This method will panic if calculating the elapsed time since the Unix epoch fails.

pub const fn from_rfc4122(ticks: u64, counter: u16) -> Timestamp

Construct a Timestamp from an RFC4122 timestamp and counter, as used in versions 1 and 6 UUIDs.

pub fn from_unix( context: impl ClockSequence<Output = u16>, seconds: u64, nanos: u32 ) -> Timestamp

Construct a Timestamp from a Unix timestamp, as used in version 7 UUIDs.

pub const fn to_unix(&self) -> (u64, u32)

Get the value of the timestamp as a Unix timestamp, as used in version 7 UUIDs.

pub const fn to_unix_nanos(&self) -> u32

👎Deprecated: use to_unix instead

Get the number of fractional nanoseconds in the Unix timestamp.

This method is deprecated and probably doesn’t do what you’re expecting it to. It doesn’t return the timestamp as nanoseconds since the Unix epoch, it returns the fractional seconds of the timestamp.

Trait Implementations

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<(), Error>

Formats the value using the given formatter.

impl Hash for Timestamp

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

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 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: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
