Struct KeyValueRef

pub struct KeyValueRef<'a> {
    pub key: &'a [u8],
    pub timestamp: u64,
    pub value: Option<&'a [u8]>,
}

A KeyValueRef is an easy-to-copy version of a key-value pair.

Fields

key: &'a [u8]

The key of this KeyValueRef.

timestamp: u64

The timestamp of this KeyValueRef.

value: Option<&'a [u8]>

The value of this KeyValueRef. None indicates a tombstone.

Trait Implementations

impl<'a> Clone for KeyValueRef<'a>

fn clone(&self) -> KeyValueRef<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for KeyValueRef<'a>

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

Formats the value using the given formatter.

impl<'a> Display for KeyValueRef<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a KeyValuePair> for KeyValueRef<'a>

fn from(kvp: &'a KeyValuePair) -> Self

Converts to this type from the input type.

impl<'a, 'b: 'a> From<&'a KeyValueRef<'b>> for KeyRef<'a>

fn from(kvr: &'a KeyValueRef<'b>) -> KeyRef<'a>

Converts to this type from the input type.

impl<'a> From<KeyValueRef<'a>> for Key

fn from(kvr: KeyValueRef<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<KeyValueRef<'a>> for KeyValuePair

fn from(kvr: KeyValueRef<'a>) -> Self

Converts to this type from the input type.

impl<'a> Ord for KeyValueRef<'a>

fn cmp(&self, rhs: &KeyValueRef<'_>) -> 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<'a> PartialEq for KeyValueRef<'a>

fn eq(&self, rhs: &KeyValueRef<'_>) -> 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<'a> PartialOrd for KeyValueRef<'a>

fn partial_cmp(&self, rhs: &KeyValueRef<'_>) -> 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.
