impl ExtensionSet for DoubleValue

const PROTO_FQN: &'static str = "google.protobuf.DoubleValue"

Fully-qualified proto type name of this message (no leading dot), e.g. "google.protobuf.FieldOptions".

fn unknown_fields(&self) -> &UnknownFields

Immutable access to the extendee’s unknown-field storage.

fn unknown_fields_mut(&mut self) -> &mut UnknownFields

Mutable access to the extendee’s unknown-field storage.

fn extension<C>(&self, ext: &Extension<C>) -> <C as ExtensionCodec>::Output

where C: ExtensionCodec,

Read an extension value.

fn set_extension<C>( &mut self, ext: &Extension<C>, value: <C as ExtensionCodec>::Value, )

where C: ExtensionCodec,

Write an extension value, replacing any prior occurrences.

fn has_extension<C>(&self, ext: &Extension<C>) -> bool

impl Message for DoubleValue

fn compute_size(&self) -> u32

Returns the total encoded size in bytes.

The result is a u32; the protobuf specification requires all messages to fit within 2 GiB (2,147,483,647 bytes), so a compliant message will never overflow this type.

fn write_to(&self, buf: &mut impl BufMut)

Write this message’s encoded bytes to a buffer.

fn merge_field( &mut self, tag: Tag, buf: &mut impl Buf, depth: u32, ) -> Result<(), DecodeError>

Processes a single already-decoded tag and its associated field data from buf.

fn cached_size(&self) -> u32

The cached encoded size from the last compute_size() call.

fn clear(&mut self)

Clear all fields to their default values.

fn encode(&self, buf: &mut impl BufMut)

Convenience: compute size, then write. This is the primary encoding API.

fn encode_length_delimited(&self, buf: &mut impl BufMut)

Encode this message as a length-delimited byte sequence.

fn encode_to_vec(&self) -> Vec<u8>

Encode this message to a new Vec<u8>.

fn encode_to_bytes(&self) -> Bytes

Encode this message to a new bytes::Bytes.

fn decode(buf: &mut impl Buf) -> Result<Self, DecodeError>

where Self: Sized,

Decode a message from a buffer.

fn decode_from_slice(data: &[u8]) -> Result<Self, DecodeError>

where Self: Sized,

Decode a message from a byte slice.

fn decode_length_delimited(buf: &mut impl Buf) -> Result<Self, DecodeError>

where Self: Sized,

Decode a length-delimited message from a buffer.

fn merge_to_limit( &mut self, buf: &mut impl Buf, depth: u32, limit: usize, ) -> Result<(), DecodeError>

Merge fields from a buffer until buf.remaining() reaches limit.

fn merge_group( &mut self, buf: &mut impl Buf, depth: u32, field_number: u32, ) -> Result<(), DecodeError>

Merges a group-encoded message from buf, reading fields until an EndGroup tag with the given field_number is encountered.

fn merge(&mut self, buf: &mut impl Buf, depth: u32) -> Result<(), DecodeError>

Merge fields from a buffer into this message.

fn merge_from_slice(&mut self, data: &[u8]) -> Result<(), DecodeError>

Merge fields from a byte slice into this message.

fn merge_length_delimited( &mut self, buf: &mut impl Buf, depth: u32, ) -> Result<(), DecodeError>

Merge fields from a length-delimited sub-message payload into this message.

impl PartialEq for DoubleValue

fn eq(&self, other: &DoubleValue) -> 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 DoubleValue

Available on crate feature json only.

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl TextFormat for DoubleValue

fn encode_text(&self, enc: &mut TextEncoder<'_>) -> Result

Write this message’s fields to enc.

fn merge_text(&mut self, dec: &mut TextDecoder<'_>) -> Result<(), ParseError>

Merge fields from dec into this message.
