Struct googapis::google::spanner::v1::mutation::Write

pub struct Write {
    pub table: String,
    pub columns: Vec<String>,
    pub values: Vec<ListValue>,
}

Arguments to [insert][google.spanner.v1.Mutation.insert], [update][google.spanner.v1.Mutation.update], [insert_or_update][google.spanner.v1.Mutation.insert_or_update], and [replace][google.spanner.v1.Mutation.replace] operations.

Fields

table: String

Required. The table whose rows will be written.

columns: Vec<String>

The names of the columns in [table][google.spanner.v1.Mutation.Write.table] to be written.

The list of columns must contain enough columns to allow Cloud Spanner to derive values for all primary key columns in the row(s) to be modified.

values: Vec<ListValue>

The values to be written. values can contain more than one list of values. If it does, then multiple rows are written, one for each entry in values. Each list in values must have exactly as many entries as there are entries in [columns][google.spanner.v1.Mutation.Write.columns] above. Sending multiple lists is equivalent to sending multiple Mutations, each containing one values entry and repeating [table][google.spanner.v1.Mutation.Write.table] and [columns][google.spanner.v1.Mutation.Write.columns]. Individual values in each list are encoded as described [here][google.spanner.v1.TypeCode].

Trait Implementations

impl Clone for Write

fn clone(&self) -> Write

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Write

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

Formats the value using the given formatter.

impl Default for Write

fn default() -> Self

Returns the “default value” for a type.

impl Message for Write

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,

) -> 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,

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,

impl PartialEq<Write> for Write

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

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

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

This method tests for !=.
