Struct google_api_proto::google::spanner::executor::v1::ReadAction

pub struct ReadAction {
    pub table: String,
    pub index: Option<String>,
    pub column: Vec<String>,
    pub keys: Option<KeySet>,
    pub limit: i32,
}

A single read request.

Fields

table: String

The table to read at.

index: Option<String>

The index to read at if it’s an index read.

column: Vec<String>

List of columns must begin with the key columns used for the read.

keys: Option<KeySet>

Keys for performing this read.

limit: i32

Limit on number of rows to read. If set, must be positive.

Implementations

impl ReadAction

pub fn index(&self) -> &str

Returns the value of index, or the default value if index is unset.

Trait Implementations

impl Clone for ReadAction

fn clone(&self) -> ReadAction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReadAction

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

Formats the value using the given formatter.

impl Default for ReadAction

fn default() -> Self

Returns the “default value” for a type.

impl Message for ReadAction

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

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

where Self: Sized,

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

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

where Self: Sized,

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

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

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

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

where Self: Sized,

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

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

where Self: Sized,

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

impl PartialEq for ReadAction

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
