Struct pancake_engine_ssi::lsm::unit::commit_info::ReplacementNum

pub struct ReplacementNum(u64);

The ordered number that disambiguates 2+ CommitInfo instances.

In case 2+ CommitInfos overlap in their CommitVer intervals, this number indicates the new-ness of each CommitInfo.

When loading a collection of overlapping CommitInfos, all among them with the largest ReplacementNum should be retained, and all other others should be ignored and discarded.

Trait Implementations

impl Clone for ReplacementNum

fn clone(&self) -> ReplacementNum

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for ReplacementNum

fn cmp(&self, other: &ReplacementNum) -> 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 PartialEq for ReplacementNum

fn eq(&self, other: &ReplacementNum) -> 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 PartialOrd for ReplacementNum

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