let message: &MyMessage = message;
let any = Any::pack(message)?;
assert!(any.is::<MyMessage>());

pub fn pack_dyn(message: &dyn Message) -> ProtobufResult<Any>

Examples

use protobuf::Message;
use protobuf::well_known_types::Any;

let message: &dyn Message = message;
let any = Any::pack_dyn(message)?;
assert!(any.is_dyn(message.descriptor()));

pub fn is<M: Message>(&self) -> bool

Check if Any contains a message of given type.

pub fn is_dyn(&self, descriptor: &MessageDescriptor) -> bool

Check if Any contains a message of given type.

pub fn unpack<M: Message>(&self) -> ProtobufResult<Option<M>>

Extract a message from this Any.

Returns

• Ok(None) when message type mismatch
• Err when parse failed

pub fn unpack_dyn( &self, descriptor: &MessageDescriptor, ) -> ProtobufResult<Option<Box<dyn Message>>>

Extract a message from this Any.

Returns

• Ok(None) when message type mismatch
• Err when parse failed

Trait Implementations
