Struct proc_macro::Punct

1.29.0 · source ·
pub struct Punct(/* private fields */);
Expand description

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.

Implementations§

source§

impl Punct

source

pub 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.

source

pub fn as_char(&self) -> char

Returns the value of this punctuation character as char.

source

pub 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 the operator has certainly ended (Alone).

source

pub fn span(&self) -> Span

Returns the span for this punctuation character.

source

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

Configure the span for this punctuation character.

impl PartialEq<Punct> for char

source§

fn eq(&self, rhs: &Punct) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
