Implementations§

impl TokenKind

pub(crate) fn keyword(text: &str) -> Option<Self>

pub const fn text(self) -> Option<&'static str>

How a keyword, punctuation or operator token is spelled, or None for tokens whose text varies, such as names and numbers.

pub fn describe(self) -> Cow<'static, str>

How the token reads in an error message.

const fn spelling(self) -> Spelling
