Struct sp_timestamp::Timestamp

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

Unit type wrapper that represents a timestamp.

Such a timestamp is the time since the UNIX_EPOCH in milliseconds at a given point in time.

Implementations

impl Timestamp

pub const fn new(inner: u64) -> Self

Create new Self.

pub const fn as_duration(self) -> Duration

Returns self as Duration.

pub const fn as_millis(&self) -> u64

Returns self as a u64 representing the elapsed time since the UNIX_EPOCH in milliseconds.

pub fn checked_sub(self, other: Self) -> Option<Self>

Checked subtraction that returns None on an underflow.

pub fn current() -> Self

The current timestamp using the system time.

Methods from Deref<Target = u64>

pub const MIN: u64 = 0u64

pub const MAX: u64 = 18_446_744_073_709_551_615u64

pub const BITS: u32 = 64u32

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Default for Timestamp

fn default() -> Timestamp

Returns the “default value” for a type.

impl Deref for Timestamp

type Target = u64

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for Timestamp

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

Formats the value using the given formatter.

impl Encode for Timestamp

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback ) -> __CodecOutputReturn

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<Duration> for Timestamp

fn from(duration: Duration) -> Self

Converts to this type from the input type.

impl From<Timestamp> for u64

fn from(timestamp: Timestamp) -> u64

Converts to this type from the input type.

impl From<u64> for Timestamp

fn from(timestamp: u64) -> Self

Converts to this type from the input type.

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 + PartialOrd,

Restrict a value to a certain interval.

impl<T: Into<u64> + Copy> PartialEq<T> for Timestamp

fn eq(&self, eq: &T) -> 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.

impl<T: Into<u64> + Copy> PartialOrd<T> for Timestamp

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