Enum Tok 

pub enum Tok {
    Word {
        upper: String,
        raw: String,
    },
    Quoted(String),
    Str(String),
    Num(f64),
    Op(String),
    Punct(char),
    Eof,
}

Variants

Word

A bare identifier or keyword, with its canonical UPPERCASE form and the raw spelling. Both are kept for the same reason NQL keeps both: a column may legitimately be called count or value, and folding case at the lexer would look up a key the data does not have.

Fields

upper: String

raw: String

Quoted(String)

A "double quoted" identifier. Case is significant and it is NEVER a keyword — "select" is a column named select.

Str(String)

A 'single quoted' string literal, with '' already collapsed.

Num(f64)

Op(String)

Punct(char)

Eof
