Trait MessageDecode

pub trait MessageDecode<'a, T, R>: Sized {
    // Required method
    fn read_message(
        item: &mut InplaceOption<'_, T>,
        reader: MessageReader<'a, '_, R>,
    ) -> Result<(), Error>;
}

The MessageEncode trait provides a message decoder for type T.

R is the external resource type, which allows decoding objects with non-protobuf resources such as file descriptors. Most implementors of this trait will be generic over all R.

Required Methods

fn read_message( item: &mut InplaceOption<'_, T>, reader: MessageReader<'a, '_, R>, ) -> Result<(), Error>

Reads a message into item.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
