Struct KeyRef

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

impl<'a> Ord for KeyRef<'a>

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

fn eq(&self, rhs: &Bound<KeyRef<'_>>) -> 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.
