Methods

impl Matches

pub fn opt_present(&self, nm: &str) -> bool

Returns true if an option was matched.

pub fn opt_count(&self, nm: &str) -> usize

Returns the number of times an option was matched.

pub fn opts_present(&self, names: &[String]) -> bool

Returns true if any of several options were matched.

pub fn opts_str(&self, names: &[String]) -> Option<String>

Returns the string argument supplied to one of several matching options or None.

pub fn opt_strs(&self, nm: &str) -> Vec<String>

Returns a vector of the arguments provided to all matches of the given option.

Used when an option accepts multiple values.

pub fn opt_str(&self, nm: &str) -> Option<String>

Returns the string argument supplied to a matching option or None.

pub fn opt_default(&self, nm: &str, def: &str) -> Option<String>

Returns the matching string, a default, or None.

Returns None if the option was not present, def if the option was present but no argument was provided, and the argument if the option was present and an argument was provided.
