Enum palex::TokenKind

pub enum TokenKind {
    NoDash,
    OneDash,
    TwoDashes,
    AfterOneDash,
    AfterEquals,
}

The kind of the current token.

This enum acts as the state of the currently parsed argument; this is necessary because an argument can consist of multiple tokens.

Variants

NoDash

An argument that doesn't start with dashes, e.g. program.

OneDash

An argument that starts with exactly 1 dash, e.g. -foo, -V, -h=config.

TwoDashes

An argument that starts with 2 or more dashes, e.g. --version or --help=config.

AfterOneDash

An option or value of a single-dash argument, after an option has been eaten.

Example when parsing -abcd=efg,hij

abcd=efg    # OneDash
 bcd=efg    # AfterOneDash
  cd=efg    # AfterOneDash
     efg    # AfterEquals

AfterEquals

A value of an argument after the =, after the name of the argument has been eaten.

Example when parsing --abcd=efg,hij

abcd=efg,hij    # TwoDashes
     efg,hij    # AfterEquals
         hij    # AfterEquals
