Struct proc_macro::Punct 1.29.0[−][src]
pub struct Punct(_);
An Punct is an single punctuation character like +, - or #.
Multi-character operators like += are represented as two instances of Punct with different
forms of Spacing returned.
Implementations
impl Punct[src]
impl Punct[src]pub fn new(ch: char, spacing: Spacing) -> 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.
pub fn as_char(&self) -> char[src]
Returns the value of this punctuation character as char.
pub fn spacing(&self) -> Spacing[src]
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.
pub fn span(&self) -> Span[src]
Returns the span for this punctuation character.
pub fn set_span(&mut self, span: Span)[src]
Configure the span for this punctuation character.
Trait Implementations
impl Display for Punct[src]
impl Display for Punct[src]Prints the punctuation character as a string that should be losslessly convertible back into the same character.
