# Struct proc_macro2::Punct [−] [src]

    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.

## Implementations

### `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 multicharacter 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.
