Struct googapis::google::firestore::v1beta1::Write

pub struct Write {
    pub update_mask: Option<DocumentMask>,
    pub update_transforms: Vec<FieldTransform>,
    pub current_document: Option<Precondition>,
    pub operation: Option<Operation>,
}

A write on a document.

Fields

update_mask: Option<DocumentMask>

The fields to update in this write.

This field can be set only when the operation is update. If the mask is not set for an update and the document exists, any existing data will be overwritten. If the mask is set and the document on the server has fields not covered by the mask, they are left unchanged. Fields referenced in the mask, but not present in the input document, are deleted from the document on the server. The field paths in this mask must not contain a reserved field name.

update_transforms: Vec<FieldTransform>

The transforms to perform after update.

This field can be set only when the operation is update. If present, this write is equivalent to performing update and transform to the same document atomically and in order.

current_document: Option<Precondition>

An optional precondition on the document.

The write will fail if this is set and not met by the target document.

operation: Option<Operation>

The operation to execute.

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,

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,
