Struct protobuf::reflect::MessageDescriptor

pub struct MessageDescriptor { /* fields omitted */ }

Dynamic representation of message type.

Used for reflection.

Implementations

impl MessageDescriptor

pub fn get_proto(&self) -> &DescriptorProto

Get underlying DescriptorProto object.

pub fn get_name(&self) -> &str

Message name as specified in .proto file.

pub fn get_enums(&self) -> Vec<EnumDescriptor>

Get enums declared in this message.

pub fn for_type<M: Message>() -> MessageDescriptor

Get a message descriptor for given message type

pub fn get_nested_messages(&self) -> Vec<MessageDescriptor>

Messages declared in this messages.

pub fn file_descriptor(&self) -> &FileDescriptor

FileDescriptor containing this message.

pub fn file_descriptor_proto(&self) -> &FileDescriptorProto

FileDescriptorProto containg this message type

pub fn is_map_entry(&self) -> bool

This message descriptor is a map entry.

pub fn new_instance(&self) -> Box<dyn MessageDyn>

New empty message.

Panics

If this message is a map entry message.

pub fn default_instance(&self) -> Option<&'static dyn MessageDyn>

Shared immutable empty message.

Returns None for dynamic message.

Panics

If this message is a map entry message.

pub fn eq(&self, a: &dyn MessageDyn, b: &dyn MessageDyn) -> bool

Check if two messages equal.

Panics

Is any message has different type than this descriptor.

pub fn name(&self) -> &str

Message name as given in .proto file

pub fn full_name(&self) -> &str

Fully qualified protobuf message name

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

Message field descriptors.

pub fn oneofs<'a>(
    &'a self
) -> impl ExactSizeIterator<Item = OneofDescriptor> + 'a

Nested oneofs

pub fn get_field_by_name<'a>(&'a self, name: &str) -> Option<FieldDescriptor>

Find message field by protobuf field name

Note: protobuf field name might be different for Rust field name.

pub fn get_field_by_name_or_json_name<'a>(
    &'a self,
    name: &str
) -> Option<FieldDescriptor>

Find message field by field name or field JSON name

pub fn get_field_by_number(&self, number: u32) -> Option<FieldDescriptor>

Find message field by field name
