Implementations

impl Epoch

pub fn now() -> Self

pub fn next(self) -> Self

pub fn physical_time(&self) -> u64

milliseconds since the RisingWave epoch

pub fn from_physical_time(time: u64) -> Self

pub fn from_unix_millis(mi: u64) -> Self

pub fn from_unix_millis_or_earliest(mi: u64) -> Self

pub fn physical_now() -> u64

pub fn as_unix_millis(&self) -> u64

pub fn as_unix_secs(&self) -> u64

pub fn as_timestamptz(&self) -> Timestamptz

Returns the epoch in a Timestamptz.

pub fn as_scalar(&self) -> ScalarImpl

Returns the epoch in a Timestamptz scalar.

pub fn as_system_time(&self) -> SystemTime

Returns the epoch in real system time.

pub fn subtract_ms(&self, relative_time_ms: u64) -> Self

Returns the epoch subtract relative_time_ms, which used for ttl to get epoch corresponding to the lowerbound timepoint (src/storage/src/hummock/iterator/forward_user.rs)

Trait Implementations

impl Clone for Epoch

fn clone(&self) -> Epoch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Epoch

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

Formats the value using the given formatter.

impl Display for Epoch

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

Formats the value using the given formatter.

impl From<u64> for Epoch

fn from(epoch: u64) -> Self

Converts to this type from the input type.

impl Hash for Epoch

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 Epoch

fn cmp(&self, other: &Epoch) -> 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 Epoch

fn eq(&self, other: &Epoch) -> 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 Epoch

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