Struct KeyRange 

pub struct KeyRange { /* private fields */ }

A half-open or closed key range description.

Implementations

impl KeyRange

pub const fn new(start: Option<Key>, end: Option<Key>) -> KeyRange

Creates a key range from optional bounds.

pub fn starting_at(start: Key) -> KeyRange

Creates a range starting at start.

pub fn ending_at(end: Key) -> KeyRange

Creates a range ending at end.

pub const fn start(&self) -> Option<&Key>

Returns the start bound.

pub const fn end(&self) -> Option<&Key>

Returns the end bound.

Trait Implementations

impl Clone for KeyRange

fn clone(&self) -> KeyRange

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyRange

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

Formats the value using the given formatter.

impl Default for KeyRange

fn default() -> KeyRange

Returns the “default value” for a type.

impl PartialEq for KeyRange

fn eq(&self, other: &KeyRange) -> 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.
