Enum Token 

pub enum Token {
    Ident(String),
    Number(f64),
    LeftParen,
    RightParen,
    Comma,
    Empty,
    Eof,
}

One lexeme of a WKT string.

Mirrors the token classes the boost::tokenizer in boost/geometry/io/wkt/read.hpp separates on: a keyword/identifier, a number, the three punctuation marks, and end-of-input. EMPTY is broken out as its own token (rather than folded into Ident) so the parser can branch on <TYPE> EMPTY without re-comparing strings.

Variants

Ident(String)

An uppercased keyword — a geometry type (POINT, LINESTRING, …) or an OGC dimension suffix (Z, M, ZM).

Number(f64)

A numeric literal, already parsed to f64 (signed, decimal, E-notation).

LeftParen

(

RightParen

)

Comma

,

Empty

The EMPTY keyword.

Eof

End of input.
