Trait mail_internals::encoder::EncodableInHeader

pub trait EncodableInHeader: Send + Sync + Any + Debug {
    fn encode(&self, encoder: &mut EncodingWriter) -> Result<(), EncodingError>;
    fn boxed_clone(&self) -> Box<dyn EncodableInHeader>;
}

Trait Implemented by "components" used in header field bodies

This trait can be turned into a trait object allowing runtime genericallity over the "components" if needed.

Required methods

fn encode(&self, encoder: &mut EncodingWriter) -> Result<(), EncodingError>

fn boxed_clone(&self) -> Box<dyn EncodableInHeader>
