Enum GrammarContext 

pub enum GrammarContext {
    AllowRegExp,
    AllowDiv,
    AllowJSXIdentifier,
    Type,
}

The grammar context affecting how some tokens are lexed (e.g. / as a division operator vs. a regular-expression literal). Port of JSLexer::GrammarContext.

Variants

AllowRegExp

A RegExp can follow, so / starts a regular-expression literal.

AllowDiv

/ can follow, so it is scanned as the division operator.

AllowJSXIdentifier

/ can follow, - is part of identifiers, and > is scanned as its own token.

Type

A type annotation: / can follow, >> scans as two separate > tokens, and legacy octal literals are rejected as in strict mode.
