[][src]Enum xflag::Argument

pub enum Argument {

The type of argument encountered.



Flag without a value, e.g. -h.


An option, or a flag with a value, e.g. -fbar.

Since a flag is always exactly the width of one character, the value will be the strong that follows until a space separator is found. For example -fbar will mean the flag is f with a value of bar.


Flag indicating a line number location.

This is recognised by a + followed by a positive integer, for example +42.


Position argument that is not a flag or a value associated with a flag.


Position argument indicating /dev/stdin, e.g. -.


impl Argument[src]

pub fn as_str(&self) -> Option<&str>[src]

Get the flag's value, if it has one.
