Struct proc_macro::Punct

1.29.0 · source · []
pub struct Punct(_);
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

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 multi-character 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.
