Enum Marked 

pub enum Marked<D> {
    Normal(D),
    TombStone,
}

Data that can be marked as tombstone.

Tombstones are always greater than normal values for ordering.

use seq_marked::Marked;

let data = Marked::Normal("hello");
let tombstone = Marked::<&str>::TombStone;
assert!(tombstone > data);

Variants

Normal(D)

Normal data.

TombStone

Deletion marker.

Trait Implementations

impl<D: Clone> Clone for Marked<D>

fn clone(&self) -> Marked<D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<D: Debug> Debug for Marked<D>

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

Formats the value using the given formatter.

impl<D> Display for Marked<D>

where D: Display,

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

Formats the value using the given formatter.

impl<M> From<Marked<(Option<M>, String)>> for Marked<(Option<M>, Vec<u8>)>

fn from(value: Marked<(Option<M>, String)>) -> Self

Convert Marked<String> to Marked<Vec<u8>>

impl<D: Ord> Ord for Marked<D>

fn cmp(&self, other: &Marked<D>) -> 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<D: PartialEq> PartialEq for Marked<D>

fn eq(&self, other: &Marked<D>) -> 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<D: PartialOrd> PartialOrd for Marked<D>

fn partial_cmp(&self, other: &Marked<D>) -> 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<M> TryFrom<Marked<(Option<M>, Vec<u8>)>> for Marked<(Option<M>, String)>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(marked: Marked<(Option<M>, Vec<u8>)>) -> Result<Self, Self::Error>

Performs the conversion.

impl<D: Copy> Copy for Marked<D>

impl<D: Eq> Eq for Marked<D>
