Expand description

The result of checking command line arguments. Contains a vector of matches and a vector of free strings.

free: Vec<String>

Free string fragments

Implementations

Returns true if an option was defined

Returns true if an option was matched.

Returns the number of times an option was matched.

Returns a vector of all the positions in which an option was matched.

Returns true if any of several options were matched.

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

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

Used when an option accepts multiple values.

Returns a vector of the arguments provided to all matches of the given option, together with their positions.

Used when an option accepts multiple values.

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

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.

Returns some matching value or None.

Similar to opt_str, also converts matching argument using FromStr.

Returns a matching value or default.

Similar to opt_default, except the two differences. Instead of returning None when argument was not present, return def. Instead of returning &str return type T, parsed using str::parse().
