Struct prost_wkt_types::Empty

pub struct Empty {}

A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance:

 service Foo {
   rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
 }

The JSON representation for Empty is empty JSON object {}.

Trait Implementations

impl Clone for Empty

fn clone(&self) -> Empty

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Empty

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

Formats the value using the given formatter.

impl Default for Empty

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Empty

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<()> for Empty

fn from(_value: ()) -> Self

Converts to this type from the input type.

impl Message for Empty

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 MessageSerde for Empty

fn package_name(&self) -> &'static str

package name as in proto file

fn message_name(&self) -> &'static str

message name as in proto file

fn type_url(&self) -> &'static str

the message proto type url e.g. type.googleapis.com/my.package.MyMessage

fn new_instance( &self, data: Vec<u8>, ) -> Result<Box<dyn MessageSerde>, DecodeError>

Creates a new instance of this message using the protobuf encoded data

fn try_encoded(&self) -> Result<Vec<u8>, EncodeError>

Returns the encoded protobuf message as bytes

impl Name for Empty

const PACKAGE: &'static str = "google.protobuf"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

const NAME: &'static str = "Empty"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

impl PartialEq for Empty

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

impl Serialize for Empty

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Empty

impl StructuralPartialEq for Empty
