Struct 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'");
}

Trait Implementations

impl Clone for Mailcap

fn clone(&self) -> Mailcap

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Mailcap

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Mailcap

fn default() -> Mailcap

Returns the “default value” for a type.

impl PartialEq for Mailcap

fn eq(&self, other: &Mailcap) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
