pub fn content_type(&self) -> Option<&str>

Get destination Content-Type metadata.

pub fn content_disposition(&self) -> Option<&str>

Get destination Content-Disposition metadata.

pub fn content_encoding(&self) -> Option<&str>

Get destination Content-Encoding metadata.

pub fn cache_control(&self) -> Option<&str>
