Struct Declaration 

pub struct Declaration {
    pub number: Option<i32>,
    pub full_name: Option<String>,
    pub type: Option<String>,
    pub reserved: Option<bool>,
    pub repeated: Option<bool>,
    /* private fields */
}

Fields

number: Option<i32>

The extension number declared within the extension range.

Field 1: number

full_name: Option<String>

The fully-qualified name of the extension field. There must be a leading dot in front of the full name.

Field 2: full_name

type: Option<String>

The fully-qualified type name of the extension field. Unlike Metadata.type, Declaration.type must have a leading dot for messages and enums.

Field 3: type

reserved: Option<bool>

If true, indicates that the number is reserved in the extension range, and any extension field with the number will fail to compile. Set this when a declared extension field is deleted.

Field 5: reserved

repeated: Option<bool>

If true, indicates that the extension must be defined as repeated. Otherwise the extension must be defined as optional.

Field 6: repeated

Return a reference to the single default instance of this type.

impl ExtensionSet for Declaration

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

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

where C: ExtensionCodec,

Returns true if any record at the extension’s field number is present.

fn clear_extension<C>(&mut self, ext: &Extension<C>)

fn extension_or_default<C>( &self, ext: &Extension<C>, ) -> <C as ExtensionCodec>::Value

where C: ExtensionCodec<Output = Option<<C as ExtensionCodec>::Value>>, <C as ExtensionCodec>::Value: Default,

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 Declaration

fn compute_size(&self, _cache: &mut SizeCache) -> 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, _cache: &mut SizeCache, buf: &mut impl BufMut)

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, depth: u32, ) -> 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 BufMut)

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

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

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

fn encoded_len(&self) -> u32

Compute the encoded byte size of this message.

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 MessageName for Declaration

const PACKAGE: &'static str = "google.protobuf"

The protobuf package the message is declared in.

const NAME: &'static str = "ExtensionRangeOptions.Declaration"

The unqualified message name, with . between nesting levels.

const FULL_NAME: &'static str = "google.protobuf.ExtensionRangeOptions.Declaration"

The fully-qualified protobuf type name with no leading dot.

const TYPE_URL: &'static str = "type.googleapis.com/google.protobuf.ExtensionRangeOptions.Declaration"

The google.protobuf.Any.type_url form for this message.

impl PartialEq for Declaration

fn eq(&self, other: &Declaration) -> 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.
