Struct r_extcap::ExtcapFormatter

pub struct ExtcapFormatter<'a, T: ?Sized>(pub &'a T)
where
         Self: Display;

The extcap interface expects certain output “sentences” to stdout to communicate with Wireshark, like

extcap {version=1.0}{help=Some help url}

This formatter serves as a wrapper to implement that format via the Display trait, and the Extcap output can be printed out like this:

use r_extcap::interface::Metadata;

print!("{}", ExtcapFormatter(&Metadata {
    version: "1.0".into(),
    help_url: "Some help url".into(),
    display_description: "Example extcap".into(),
}));
// Output: extcap {version=1.0}{help=Some help url}{display=Example extcap}
