Enum IdentifierQuote 

pub enum IdentifierQuote {
    Symmetric(char),
    Asymmetric {
        open: char,
        close: char,
    },
}

One accepted identifier-quoting delimiter style.

SQL identifier quotes escape an embedded close delimiter by doubling it ("a""b", [a]]b], and the backtick analogue), so the escape rule is implied by the kind — there is no separate escape character. A dialect accepts a set of these (FeatureSet::identifier_quotes); the tokenizer emits a single QuotedIdent token spanning the delimiters, and stripping/unescaping into an Ident is a later stage that reads the style back from the span’s opening byte.

Variants

Symmetric(char)

Open and close are the same delimiter (", `).

Asymmetric

Distinct open/close (T-SQL [a]); only the close needs doubling to escape.

Fields

open: char

The opening delimiter character.

close: char

The closing delimiter character.
