Trait mesh_protobuf::MessageEncode

pub trait MessageEncode<T, R>: Sized {
    // Required methods
    fn write_message(item: T, writer: MessageWriter<'_, '_, R>);
    fn compute_message_size(item: &mut T, sizer: MessageSizer<'_>);
}

The MessageEncode trait provides a message encoder for type T.

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

Required Methods

fn write_message(item: T, writer: MessageWriter<'_, '_, R>)

Writes item as a message.

fn compute_message_size(item: &mut T, sizer: MessageSizer<'_>)

Computes the size of item as a message.

Encoding will panic if the write_message call writes a different number of bytes than computed by this call.

Takes a mut reference to allow mutating/stabilizing the value so that the subsequent call to write_message acts on the same value as this call.

Object Safety

This trait is not object safe.
