Struct `Punct`

pub struct Punct(pub(crate) Punct<Span>);

A Punct is a single punctuation character such as +, - or #.

Multi-character operators like += are represented as two instances of Punct with different forms of Spacing returned.

Fields

0: Punct

Implementations

`impl Punct`

fn new(ch: char, spacing: Spacing) -> Punct

Creates a new Punct from the given character and spacing. The ch argument must be a valid punctuation character permitted by the language, otherwise the function will panic.

The returned Punct will have the default span of Span::call_site() which can be further configured with the set_span method below.

fn as_char(&self) -> char

Returns the value of this punctuation character as char.

fn spacing(&self) -> Spacing

Returns the spacing of this punctuation character, indicating whether it can be potentially combined into a multi-character operator with the following token (Joint), or whether the operator has definitely ended (Alone).

fn span(&self) -> Span

Returns the span for this punctuation character.

fn set_span(&mut self, span: Span)

Configure the span for this punctuation character.
