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>,
}

Fields

number: Option<i32>

The extension number declared within the extension range.

full_name: Option<String>

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

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.

repeated: Option<bool>

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

Implementations

impl Declaration

pub fn number(&self) -> i32

Returns the value of number, or the default value if number is unset.

pub fn full_name(&self) -> &str

Returns the value of full_name, or the default value if full_name is unset.

pub fn type(&self) -> &str

Returns the value of type, or the default value if type is unset.

pub fn reserved(&self) -> bool

Returns the value of reserved, or the default value if reserved is unset.

pub fn repeated(&self) -> bool

Returns the value of repeated, or the default value if repeated is unset.

Trait Implementations

impl Clone for Declaration

fn clone(&self) -> Declaration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Declaration

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

Formats the value using the given formatter.

impl Default for Declaration

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Declaration

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for Declaration

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

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

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

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

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

where Self: Sized,

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

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

where Self: Default,

Decodes an instance of the message from a buffer.

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

where Self: Default,

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

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

where Self: Sized,

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

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

where Self: Sized,

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

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.
