Implementations§

Source§

impl Punct

Source

pub fn as_str(&self) -> &'static str

Returns a syntax representation of this punctuator.

Some punctuators have more than one valid syntax representation (for example, Punct::And can be written as AND or &). This returns one of the valid representations.
