Struct prost_types::Option

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

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

Fields

name: String

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>

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.

Trait Implementations

impl Clone for Option

fn clone(&self) -> Option

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Option

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

Formats the value using the given formatter.

impl Default for Option

fn default() -> Self

Returns the “default value” for a type.

impl Message for Option

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>where
    B: BufMut,
    Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8, Global>where
    Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>where
    B: BufMut,
    Self: Sized,

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

fn encode_length_delimited_to_vec(&self) -> Vec<u8, Global>where
    Self: Sized,

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

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

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>where
    B: Buf,
    Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>where
    B: Buf,
    Self: Sized,

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

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>where
    B: Buf,
    Self: Sized,

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

impl PartialEq<Option> for Option

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: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
