Struct Mutation 

#[non_exhaustive]
pub struct Mutation {
    pub operation: Option<Operation>,
    /* private fields */
}

A modification to one or more Cloud Spanner rows. Mutations can be applied to a Cloud Spanner database by sending them in a Commit call.

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.

operation: Option<Operation>

Required. The operation to perform.

Implementations

impl Mutation

pub fn new() -> Self

Creates a new default instance.

pub fn set_operation<T: Into<Option<Operation>>>(self, v: T) -> Self

Sets the value of operation.

Note that all the setters affecting operation are mutually exclusive.

pub fn insert(&self) -> Option<&Box<Write>>

The value of operation if it holds a Insert, None if the field is not set or holds a different branch.

pub fn set_insert<T: Into<Box<Write>>>(self, v: T) -> Self

Sets the value of operation to hold a Insert.

Note that all the setters affecting operation are mutually exclusive.

pub fn update(&self) -> Option<&Box<Write>>

The value of operation if it holds a Update, None if the field is not set or holds a different branch.

pub fn set_update<T: Into<Box<Write>>>(self, v: T) -> Self

Sets the value of operation to hold a Update.

Note that all the setters affecting operation are mutually exclusive.

pub fn insert_or_update(&self) -> Option<&Box<Write>>

The value of operation if it holds a InsertOrUpdate, None if the field is not set or holds a different branch.

pub fn set_insert_or_update<T: Into<Box<Write>>>(self, v: T) -> Self

Sets the value of operation to hold a InsertOrUpdate.

Note that all the setters affecting operation are mutually exclusive.

pub fn replace(&self) -> Option<&Box<Write>>

The value of operation if it holds a Replace, None if the field is not set or holds a different branch.

pub fn set_replace<T: Into<Box<Write>>>(self, v: T) -> Self

Sets the value of operation to hold a Replace.

Note that all the setters affecting operation are mutually exclusive.

pub fn delete(&self) -> Option<&Box<Delete>>

The value of operation if it holds a Delete, None if the field is not set or holds a different branch.

pub fn set_delete<T: Into<Box<Delete>>>(self, v: T) -> Self

Sets the value of operation to hold a Delete.

Note that all the setters affecting operation are mutually exclusive.

pub fn send(&self) -> Option<&Box<Send>>

The value of operation if it holds a Send, None if the field is not set or holds a different branch.

pub fn set_send<T: Into<Box<Send>>>(self, v: T) -> Self

Sets the value of operation to hold a Send.

Note that all the setters affecting operation are mutually exclusive.

pub fn ack(&self) -> Option<&Box<Ack>>

The value of operation if it holds a Ack, None if the field is not set or holds a different branch.

pub fn set_ack<T: Into<Box<Ack>>>(self, v: T) -> Self

Sets the value of operation to hold a Ack.

Note that all the setters affecting operation are mutually exclusive.

Trait Implementations

impl Clone for Mutation

fn clone(&self) -> Mutation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mutation

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

Formats the value using the given formatter.

impl Default for Mutation

fn default() -> Mutation

Returns the “default value” for a type.

impl Message for Mutation

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Mutation

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