Struct OneofDescriptor 

pub struct OneofDescriptor { /* private fields */ }

A oneof field in a protobuf message.

Implementations

impl OneofDescriptor

pub fn parent_pool(&self) -> &DescriptorPool

Gets a reference to the DescriptorPool this oneof is defined in.

pub fn parent_file(&self) -> FileDescriptor

Gets the FileDescriptor this oneof is defined in.

pub fn parent_message(&self) -> &MessageDescriptor

Gets a reference to the MessageDescriptor this oneof is defined in.

pub fn name(&self) -> &str

Gets the short name of the oneof, e.g. my_oneof.

pub fn full_name(&self) -> &str

Gets the full name of the oneof, e.g. my.package.MyMessage.my_oneof.

pub fn path(&self) -> &[i32]

Gets the path where this oneof is defined within the FileDescriptorProto, e.g. [4, 0, 8, 0].

See path for more details on the structure of the path.

pub fn oneof_descriptor_proto(&self) -> &OneofDescriptorProto

Gets a reference to the raw OneofDescriptorProto wrapped by this OneofDescriptor.

pub fn options(&self) -> DynamicMessage

Decodes the options defined for this OneofDescriptorProto, including any extension options.

pub fn fields(&self) -> impl ExactSizeIterator<Item = FieldDescriptor> + '_

Gets an iterator yielding a FieldDescriptor for each field of the parent message this oneof contains.

pub fn is_synthetic(&self) -> bool

Returns true if this is a synthetic oneof generated to support proto3 optional semantics.

If true, then fields will yield exactly one field, for which FieldDescriptorProto::proto3_optional returns true.

Trait Implementations

impl Clone for OneofDescriptor

fn clone(&self) -> OneofDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OneofDescriptor

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

Formats the value using the given formatter.

impl PartialEq for OneofDescriptor

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