Struct TimeKeyItem

pub struct TimeKeyItem {
    pub partition: i64,
    pub timestamp_us: i64,
}

When a TimeKey is persisted it is ordered by partition and timestamp, and compressed using the tsz_compress crate for efficient storage.

Fields

partition: i64

timestamp_us: i64

Implementations

impl TimeKeyItem

pub fn new<T: TimeKey>(key: T) -> Self

Trait Implementations

impl Add<TimeKeyItemDelta> for TimeKeyItem

type Output = TimeKeyItem

The resulting type after applying the + operator.

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

Performs the + operation.

impl Clone for TimeKeyItem

fn clone(&self) -> TimeKeyItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Compress for TimeKeyItem

type Full = TimeKeyItem

Full and Delta may differ in signedness or storage Full is the representation of the value as a whole Delta is the representation of the difference between the value and the previous value or the difference between differences

type Delta = TimeKeyItemDelta

fn into_full(self) -> Self::Full

fn into_delta(self, prev: &Self::Full) -> Self::Delta

fn into_deltadelta(self, prev_prev_row: &Self, prev_row: &Self) -> Self::Delta

impl Debug for TimeKeyItem

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

Formats the value using the given formatter.

impl Decompress for TimeKeyItem

type Full = TimeKeyItem

type Delta = TimeKeyItemDelta

fn from_full<'a>( bits: &'a BitBufferSlice, ) -> Result<(Self, &'a BitBufferSlice), &'static str>

fn from_delta<'a>( bits: &'a BitBufferSlice, prev_row: &Self, ) -> Result<(Self, &'a BitBufferSlice), &'static str>

fn from_deltadelta<'a>( bits: &'a BitBufferSlice, prev_row: &Self, prev_prev_row: &Self, ) -> Result<(Self, &'a BitBufferSlice), &'static str>

impl FromCompressBits for TimeKeyItem

fn from_bits( input: &BitBufferSlice, ) -> Result<(Self, &BitBufferSlice), &'static str>

impl IntoCompressBits for TimeKeyItem

fn into_bits(self, out: &mut BitBuffer)

impl Ord for TimeKeyItem

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

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

Tests for self and other values to be equal, and is used by ==.

const 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 TimeKeyItem

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

impl Sub for TimeKeyItem

type Output = TimeKeyItemDelta

The resulting type after applying the - operator.

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

Performs the - operation.

impl Copy for TimeKeyItem
