[][src]Enum xflag::Argument

pub enum Argument {
    Flag(char),
    Option(charString),
    Line(i64),
    Free(String),
    Stdin,
}

The type of argument encountered.

Variants

Flag(char)

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

Option(charString)

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.

Line(i64)

Flag indicating a line number location.

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

Free(String)

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

Stdin

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

Methods
