Struct KeySet 

pub struct KeySet { /* private fields */ }

A collection of Spanner keys and key ranges.

Example

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

let keyset = KeySet::builder()
    .add_key(key![1_i64])
    .add_range(KeyRange::closed_open(key![10_i64], key![100_i64]))
    .build();

Defines a collection of Cloud Spanner keys and/or key ranges. All the keys are expected to be in the same table or index. The keys need not be sorted in any particular way.

KeySets are used for delete mutations and reads.

If the same key is specified multiple times in the set (for example if two ranges, two keys, or a key and a range overlap), the Cloud Spanner backend behaves as if the key were only specified once. KeySet instances are immutable.

Implementations

impl KeySet

pub fn builder() -> KeySetBuilder

Creates a builder for KeySet.

pub fn all() -> Self

Creates a KeySet that matches all rows.

Trait Implementations

impl Clone for KeySet

fn clone(&self) -> KeySet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeySet

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

Formats the value using the given formatter.

impl Default for KeySet

fn default() -> Self

Returns the “default value” for a type.

impl From<Key> for KeySet

fn from(key: Key) -> Self

Converts to this type from the input type.

impl From<KeyRange> for KeySet

fn from(range: KeyRange) -> Self

Converts to this type from the input type.

impl PartialEq for KeySet

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