Struct proc_macro::Punct 1.29.0[−][src]
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 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.
Trait Implementations
Prints the punctuation character as a string that should be losslessly convertible back into the same character.
