Struct mailcap::Mailcap

pub struct Mailcap { /* private fields */ }

Meta representation of all available mailcap files and their combined lines.

Implementations

impl Mailcap

pub fn new() -> Result<Mailcap, MailcapError>

Returns a combined mailcap from all available default files or a $MAILCAPS env. The default list (in ascending order of importance) includes:

• /usr/local/etc/mailcap
• /usr/etc/mailcap
• /etc/mailcap
• $HOME/.mailcap

Examples

let cap = Mailcap::new()?;

Errors

If there are no available mailcap files in the default locations or no $MAILCAPS env has been set, or if the files or empty or contain no valid mailcap lines, MailcapError will be returned. The implementation is loose: as long as one file exists with at least one valid mailcap line, the Result will be Ok.

pub fn get(&self, key: &str) -> Option<&Entry>

Given a specific mime-type value, will lookup if there is an existing mailcap entry for that type.

Examples

let cap = Mailcap::new()?;
if let Some(i) = cap.get("text/html") {
    let command = i.viewer("/var/www/index.html");
    assert_eq!(command, "qutebrowser '/var/www/index.html'");
}
