Struct google_api_proto::google::watcher::v1::Change

pub struct Change {
    pub element: String,
    pub state: i32,
    pub data: Option<Any>,
    pub resume_marker: Bytes,
    pub continued: bool,
}

A Change indicates the most recent state of an element.

Fields

element: String

Name of the element, interpreted relative to the entity’s actual name. “” refers to the entity itself. The element name is a valid UTF-8 string.

state: i32

The state of the element.

data: Option<Any>

The actual change data. This field is present only when state() == EXISTS or state() == ERROR. Please see [google.protobuf.Any][google.protobuf.Any] about how to use the Any type.

resume_marker: Bytes

If present, provides a compact representation of all the messages that have been received by the caller for the given entity, e.g., it could be a sequence number or a multi-part timestamp/version vector. This marker can be provided in the Request message, allowing the caller to resume the stream watching at a specific point without fetching the initial state.

continued: bool

If true, this Change is followed by more Changes that are in the same group as this Change.

Implementations

impl Change

pub fn state(&self) -> State

Returns the enum value of state, or the default if the field is set to an invalid enum value.

pub fn set_state(&mut self, value: State)

Sets state to the provided enum value.

Trait Implementations

impl Clone for Change

fn clone(&self) -> Change

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Change

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

Formats the value using the given formatter.

impl Default for Change

fn default() -> Self

Returns the “default value” for a type.

impl Message for Change

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 Change

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