Describes a field within a message.

Fields

name: Option<String>

number: Option<i32>

label: Option<i32>

type: Option<i32>

If type_name is set, this need not be set. If both this and type_name are set, this must be one of TYPE_ENUM, TYPE_MESSAGE or TYPE_GROUP.

type_name: Option<String>

For message and enum types, this is the name of the type. If the name starts with a '.', it is fully-qualified. Otherwise, C++-like scoping rules are used to find the type (i.e. first the nested types within this message are searched, then within the parent, on up to the root namespace).

extendee: Option<String>

For extensions, this is the name of the type being extended. It is resolved in the same manner as type_name.

default_value: Option<String>

For numeric types, contains the original text representation of the value. For booleans, "true" or "false". For strings, contains the default text contents (not escaped in any way). For bytes, contains the C escaped value. All bytes >= 128 are escaped. TODO(kenton): Base-64 encode?

oneof_index: Option<i32>

If set, gives the index of a oneof in the containing type's oneof_decl list. This field is a member of that oneof.

json_name: Option<String>

JSON name of this field. The value is set by protocol compiler. If the user has set a "json_name" option on this field, that option's value will be used. Otherwise, it's deduced from the field's name by converting it to camelCase.

options: Option<FieldOptions>

Trait Implementations

impl Clone for FieldDescriptorProto

fn clone(&self) -> FieldDescriptorProto

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<FieldDescriptorProto> for FieldDescriptorProto

fn eq(&self, other: &FieldDescriptorProto) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &FieldDescriptorProto) -> bool

This method tests for !=.

impl Default for FieldDescriptorProto

fn default() -> FieldDescriptorProto

Returns the "default value" for a type.

impl Debug for FieldDescriptorProto

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

Formats the value using the given formatter.

impl Message for FieldDescriptorProto

fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

fn merge_field<B>(&mut self, buf: &mut B) -> Result<(), DecodeError> where
    B: Buf, 

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError> where
    B: BufMut, 

Encodes the message to a buffer.

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

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

fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    B: IntoBuf,
    Self: Default,

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    B: IntoBuf,
    Self: Default, 

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

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: IntoBuf, 

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

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError> where
    B: IntoBuf, 

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