Enum ActionToken 

pub enum ActionToken<'a> {
    Word(&'a str),
    Flag(Flag),
    Str(Cow<'a, str>),
    Id(Option<Cow<'a, str>>),
    Bool(bool),
    Number(usize),
    Char(char),
    Group(Vec<ActionToken<'a>>),
}

Variants

Word(&'a str)

A bare, unquoted word in the input.

Flag(Flag)

An action-specific flag in the input.

Str(Cow<'a, str>)

A quoted string in the input.

Special characters can be escaped in the same way they are within Rust strings.

Id(Option<Cow<'a, str>>)

An {id} in the input that expands in the action! macro to an identifier.

This will be None when the input is {}, and a positional argument will be used from the macro arguments instead.

Bool(bool)

A boolean in the input.

This will always be either true or false in the input.

Number(usize)

A number in the input.

This can be a simple number like 5 or 1234567, or one prefixed with 0x, 0o, or 0b in order to parse the suffix in base 16, 8 or 2 respectively.

Char(char)

A character in the input surrounded by single quotes (e.g., 'c').

Special characters can be escaped in the same way they are within Rust.

Group(Vec<ActionToken<'a>>)

A collection of tokens between parenthesis (e.g. (foo bar 5)).
