Struct KeyRange 

pub struct KeyRange { /* private fields */ }

Represents a contiguous range of keys.

Example

use google_cloud_spanner::key::KeyRange;
use google_cloud_spanner::key;

let range = KeyRange::closed_open(key![1_i64], key![10_i64]);

Implementations

impl KeyRange

pub fn closed_open(start: Key, end: Key) -> Self

Creates a key for the range [start, end).

Example

use google_cloud_spanner::key::KeyRange;
use google_cloud_spanner::key;

// Creates a key for the range [1, 10)
let range = KeyRange::closed_open(key![1_i64], key![10_i64]);

pub fn closed_closed(start: Key, end: Key) -> Self

Creates a key for the range [start, end].

Example

use google_cloud_spanner::key::KeyRange;
use google_cloud_spanner::key;

// Creates a key for the range [1, 10]
let range = KeyRange::closed_closed(key![1_i64], key![10_i64]);

pub fn open_closed(start: Key, end: Key) -> Self

Creates a key for the range (start, end].

Example

use google_cloud_spanner::key::KeyRange;
use google_cloud_spanner::key;

// Creates a key for the range (1, 10]
let range = KeyRange::open_closed(key![1_i64], key![10_i64]);

pub fn open_open(start: Key, end: Key) -> Self

Creates a key for the range (start, end).

Example

use google_cloud_spanner::key::KeyRange;
use google_cloud_spanner::key;

// Creates a key for the range (1, 10)
let range = KeyRange::open_open(key![1_i64], key![10_i64]);

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

Formats the value using the given formatter.

impl From<KeyRange> for KeySet

fn from(range: KeyRange) -> Self

Converts to this type from the input 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.
