}

Trait to support serialization and deserialization of prost messages.

Required Methods

fn message_name(&self) -> &'static str

message name as in proto file

fn package_name(&self) -> &'static str

package name as in proto file

fn type_url(&self) -> &'static str

the message proto type url e.g. type.googleapis.com/my.package.MyMessage

fn new_instance( &self, data: Vec<u8>, ) -> Result<Box<dyn MessageSerde>, DecodeError>

Creates a new instance of this message using the protobuf encoded data

fn try_encoded(&self) -> Result<Vec<u8>, EncodeError>

Returns the encoded protobuf message as bytes

Implementations

impl dyn MessageSerde

The implementation here is a direct copy of the impl dyn of std::any::Any!

pub fn is<T>(&self) -> bool

where T: MessageSerde,

Returns true if the inner type is the same as T.

pub fn downcast_ref<T>(&self) -> Option<&T>

where T: MessageSerde,

Returns some reference to the inner value if it is of type T, or None if it isn’t.

pub fn downcast_mut<T>(&mut self) -> Option<&mut T>

where T: MessageSerde,

Returns some mutable reference to the boxed value if it is of type T, or None if it isn’t.

pub unsafe fn downcast_ref_unchecked<T>(&self) -> &T

where T: MessageSerde,

Returns a reference to the inner value as type dyn T.

Safety

The contained value must be of type T. Calling this method with the incorrect type is undefined behavior.

pub unsafe fn downcast_mut_unchecked<T>(&mut self) -> &mut T

where T: MessageSerde,

Returns a mutable reference to the inner value as type dyn T.

Safety

The contained value must be of type T. Calling this method with the incorrect type is undefined behavior.

Trait Implementations

impl<'typetag> Serialize for dyn MessageSerde + 'typetag

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<'typetag> Serialize for dyn MessageSerde + Send + 'typetag

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

impl<'typetag> Serialize for dyn MessageSerde + Sync + Send + 'typetag

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl<'typetag> Serialize for dyn MessageSerde + Sync + 'typetag

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
