Struct proc_macro2::Punct [−][src]
pub struct Punct { /* fields omitted */ }
Expand description
A Punct
is a single punctuation character like +
, -
or #
.
Multicharacter 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]
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 spacing(&self) -> Spacing
[src]
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 multicharacter operator
(Joint
), or it’s followed by some other token or whitespace (Alone
)
so the operator has certainly ended.
