Fields

deprecated: Option<bool>

Note: Field numbers 1 through 32 are reserved for Google’s internal RPC framework. We apologize for hoarding these numbers to ourselves, but we were already using them long before we decided to release Protocol Buffers.

Is this method deprecated? Depending on the target platform, this can emit Deprecated annotations for the method, or it will be completely ignored; in the very least, this is a formalization for deprecating methods.

Field 33: deprecated

idempotency_level: Option<IdempotencyLevel>

Field 34: idempotency_level

features: MessageField<FeatureSet, Inline<FeatureSet>>

Any features defined in the specific edition. WARNING: This field should only be used by protobuf plugins or special cases like the proto compiler. Other uses are discouraged and developers should rely on the protoreflect APIs for their client language.

Field 35: features

uninterpreted_option: Vec<UninterpretedOption>

The parser stores options it doesn’t recognize here. See above.

Field 999: uninterpreted_option

Write an extension value, replacing any prior occurrences.

fn try_set_extension<C>( &mut self, ext: &Extension<C>, value: <C as ExtensionCodec>::Value, ) -> Result<(), EncodeError>

where C: ExtensionCodec,

Write an extension value, replacing any prior occurrences — returning an error instead of panicking if a message-typed value’s encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

Read a singular extension value, returning the proto2 [default = ...] value if absent, or the type’s Default if no proto default was declared.

impl Message for MethodOptions

fn compute_size(&self, __cache: &mut SizeCache) -> u32

Returns the total encoded size in bytes.

Accumulates in u64 (which cannot overflow for in-memory data) and saturates to u32 at return, so a message whose encoded size exceeds the 2 GiB protobuf limit yields a value above ::buffa::MAX_MESSAGE_BYTES that the encode entry points reject, never a silently wrapped size.

fn write_to(&self, __cache: &mut SizeCache, buf: &mut impl EncodeSink)

Write this message’s encoded bytes to a buffer, consuming nested-message sizes from cache (populated by a prior compute_size call on the same cache).

fn merge_field( &mut self, tag: Tag, buf: &mut impl Buf, ctx: DecodeContext<'_>, ) -> Result<(), DecodeError>

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

fn clear(&mut self)

Clear all fields to their default values.

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

Compute size, then write. This is the primary encoding API.

fn try_encode(&self, buf: &mut impl EncodeSink) -> Result<(), EncodeError>

Encode, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

fn encode_with_cache(&self, cache: &mut SizeCache, buf: &mut impl EncodeSink)

Encode using a caller-supplied SizeCache, for reuse across many encodes in a hot loop. Clears the cache first.

fn try_encode_with_cache( &self, cache: &mut SizeCache, buf: &mut impl EncodeSink, ) -> Result<(), EncodeError>

Encode with a caller-supplied SizeCache, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES). Clears the cache first.

fn try_encode_bounded( &self, max_bytes: u32, buf: &mut impl EncodeSink, ) -> Result<u32, EncodeError>

Encode this message into buf only if its encoded size fits within max_bytes, using a single size pass that is then reused for the write.

fn try_encode_bounded_with_cache( &self, max_bytes: u32, cache: &mut SizeCache, buf: &mut impl EncodeSink, ) -> Result<u32, EncodeError>

Like try_encode_bounded but reuses an existing SizeCache, clearing it first.

fn encoded_len(&self) -> u32

Compute the encoded byte size of this message.

fn try_encoded_len(&self) -> Result<u32, EncodeError>

Compute the encoded byte size, returning an error instead of panicking if it exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

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

Encode this message as a length-delimited byte sequence.

fn try_encode_length_delimited( &self, buf: &mut impl EncodeSink, ) -> Result<(), EncodeError>

Encode as a length-delimited byte sequence, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

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

Encode this message to a new Vec<u8>.

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

Encode to a new Vec<u8>, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_BYTES).

fn encode_to_bytes(&self) -> Bytes

Encode this message to a new bytes::Bytes.

fn try_encode_to_bytes(&self) -> Result<Bytes, EncodeError>

Encode to a new bytes::Bytes, returning an error instead of panicking if the encoded size exceeds the 2 GiB protobuf limit (MAX_MESSAGE_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, ctx: DecodeContext<'_>, limit: usize, ) -> Result<(), DecodeError>

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

fn merge_group( &mut self, buf: &mut impl Buf, ctx: DecodeContext<'_>, 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, ctx: DecodeContext<'_>, ) -> 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, ctx: DecodeContext<'_>, ) -> Result<(), DecodeError>
