Struct FeatureSupport 

pub struct FeatureSupport {
    pub edition_introduced: Option<Edition>,
    pub edition_deprecated: Option<Edition>,
    pub deprecation_warning: Option<String>,
    pub edition_removed: Option<Edition>,
    /* private fields */
}

Information about the support window of a feature.

Fields

edition_introduced: Option<Edition>

The edition that this feature was first available in. In editions earlier than this one, the default assigned to EDITION_LEGACY will be used, and proto files will not be able to override it.

Field 1: edition_introduced

edition_deprecated: Option<Edition>

The edition this feature becomes deprecated in. Using this after this edition may trigger warnings.

Field 2: edition_deprecated

deprecation_warning: Option<String>

The deprecation warning text if this feature is used after the edition it was marked deprecated in.

Field 3: deprecation_warning

edition_removed: Option<Edition>

The edition this feature is no longer available in. In editions after this one, the last default assigned will be used, and proto files will not be able to override it.

Field 4: edition_removed

impl Message for FeatureSupport

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>
