Struct googapis::google::spanner::v1::KeySet

pub struct KeySet {
    pub keys: Vec<ListValue>,
    pub ranges: Vec<KeyRange>,
    pub all: bool,
}

KeySet 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.

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), Cloud Spanner behaves as if the key were only specified once.

Fields

keys: Vec<ListValue>

A list of specific keys. Entries in keys should have exactly as many elements as there are columns in the primary or index key with which this KeySet is used. Individual key values are encoded as described [here][google.spanner.v1.TypeCode].

ranges: Vec<KeyRange>

A list of key ranges. See [KeyRange][google.spanner.v1.KeyRange] for more information about key range specifications.

all: bool

For convenience all can be set to true to indicate that this KeySet matches all keys in the table or index. Note that any keys specified in keys or ranges are only yielded once.

Trait Implementations

impl Clone for KeySet

fn clone(&self) -> KeySet

Returns a copy 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 Message for KeySet

fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

fn merge_field<B>(
    &mut self,
    tag: u32,
    wire_type: WireType,
    buf: &mut B,
    ctx: DecodeContext
) -> Result<(), DecodeError> where
    B: Buf, 

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8, Global>

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8, Global>

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, 

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq<KeySet> for KeySet

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &KeySet) -> bool

This method tests for !=.
