[][src]Struct proc_macro2::Punct

pub struct Punct { /* fields omitted */ }

An Punct is an single punctuation character like +, - or #.

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

Methods

impl Punct
[src]

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.

Returns the value of this punctuation character as char.

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.

Returns the span for this punctuation character.

Configure the span for this punctuation character.
