Struct Write 

#[non_exhaustive]
pub struct Write {
    pub table: String,
    pub columns: Vec<String>,
    pub values: Vec<ListValue>,
    /* private fields */
}

Arguments to insert, update, insert_or_update, and replace operations.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

table: String

Required. The table whose rows will be written.

columns: Vec<String>

The names of the columns in 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 above. Sending multiple lists is equivalent to sending multiple Mutations, each containing one values entry and repeating table and columns. Individual values in each list are encoded as described here.

Implementations

impl Write

pub fn new() -> Self

Creates a new default instance.

pub fn set_table<T: Into<String>>(self, v: T) -> Self

Sets the value of table.

pub fn set_columns<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<String>,

Sets the value of columns.

pub fn set_values<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<ListValue>,

Sets the value of values.

Trait Implementations

impl Clone for Write

fn clone(&self) -> Write

Returns a duplicate 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() -> Write

Returns the “default value” for a type.

impl Message for Write

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Write

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