pub fn is_map_entry(&self) -> bool

This message descriptor is a map entry.

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

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 + 'static), b: &(dyn MessageDyn + 'static), ) -> bool

Check if two messages equal.

Panics

Is any message has different type than this descriptor.

Message field descriptors.

pub fn extensions(&self) -> impl Iterator<Item = FieldDescriptor>

Extension fields.

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

Trait Implementations

impl Clone for LuaMessageDescriptor

fn clone(&self) -> LuaMessageDescriptor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Deref for LuaMessageDescriptor

type Target = MessageDescriptor

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<LuaMessageDescriptor> for MessageDescriptor

fn from(value: LuaMessageDescriptor) -> Self

Converts to this type from the input type.

impl From<MessageDescriptor> for LuaMessageDescriptor

fn from(value: MessageDescriptor) -> Self

Converts to this type from the input type.

impl Hash for LuaMessageDescriptor

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 PartialEq for LuaMessageDescriptor

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

fn add_fields<F>(fields: &mut F)

where F: UserDataFields<Self>,
