Struct `Punct`

struct Punct { ... }

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

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

Implementations

`impl Punct`

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

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: &Self) -> char

Returns the value of this punctuation character as char.

fn spacing(self: &Self) -> Spacing

Returns the spacing of this punctuation character, indicating whether it's immediately followed by another Punct in the token stream, so they can potentially be combined into a multicharacter operator (Joint), or it's followed by some other token or whitespace (Alone) so the operator has certainly ended.

fn span(self: &Self) -> Span

Returns the span for this punctuation character.

fn set_span(self: &mut Self, span: Span)

Configure the span for this punctuation character.
