Trait ReflectMessage 

pub trait ReflectMessage {
    // Required method
    fn descriptor(&self) -> MessageDescriptor;

    // Provided method
    fn transcode_to_dynamic(&self) -> DynamicMessage
       where Self: Message + Sized { ... }
}

Implemented by every type that has a descriptor in some crate::DescriptorPool — generated typed messages via #[derive(ReflectMessage)] and runtime-typed crate::DynamicMessage.

Note: this trait deliberately does not require buffa::Message as a super-trait so that crate::DynamicMessage (which has no static DefaultInstance) can implement it. Where wire-encoding via Self::encode_to_vec is needed, individual methods name Self: ::buffa::Message as a where-clause.

Required Methods

fn descriptor(&self) -> MessageDescriptor

Resolve the MessageDescriptor for Self.

The pool the descriptor lives in is set up by the #[derive(ReflectMessage)] macro, either:

• the user-supplied descriptor_pool expression, or
• a lazily-decoded pool keyed off the embedded file_descriptor_set_bytes.

Provided Methods

fn transcode_to_dynamic(&self) -> DynamicMessage

where Self: Message + Sized,

Available on crate feature dynamic only.

Round-trip self through wire bytes into a crate::DynamicMessage.

The default implementation pays one wire round-trip; the impl for crate::DynamicMessage short-circuits to self.clone().

Panics

Panics if self.encode_to_vec() produces bytes that fail to decode against self.descriptor() — this would indicate a bug in the generated descriptor() wiring or in self’s Message impl.
