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>

Implementations

impl dyn EncodableInHeader

pub fn is<T: EncodableInHeader>(&self) -> bool
