Struct prost_types::Option

[+] Show declaration

pub struct Option {
    pub name: String,
    pub value: Option<Any>,
}

[−] Expand description

A protocol buffer option, which can be attached to a message, field, enumeration, etc.

Fields

name: String

[−] Expand description

The option’s name. For protobuf built-in options (options defined in descriptor.proto), this is the short name. For example, "map_entry". For custom options, it should be the fully-qualified name. For example, "google.api.http".

value: Option<Any>

[−] Expand description

The option’s value packed in an Any message. If the value is a primitive, the corresponding wrapper type defined in google/protobuf/wrappers.proto should be used. If the value is an enum, it should be stored as an int32 value using the google.protobuf.Int32Value type.

impl Message for Option[+]

[+] Show hidden undocumented items

fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

fn merge_field<B>(
    &mut self,
    tag: u32,

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.

pub fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, [−]

Encodes the message to a buffer.

pub fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, [−]

Encodes the message with a length-delimiter to a buffer.

pub fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, [−]

Decodes an instance of the message from a buffer.

pub 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.

pub fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, [−]

Decodes an instance of the message from a buffer, and merges it into self.

pub fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: Buf, [−]

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq<Option> for Option[+]

[+] Show hidden undocumented items

fn eq(&self, other: &Option) -> bool[−]

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Option) -> bool[−]

This method tests for !=.
