Expand description

The unit of lexical syntax.

Variants§

§

BracketClose

An closing bracket.

§

BracketOpen

An opening bracket.

§

Comment(usize, &'a str)

A comment. The numeric parameter is the number of “extra” semicolons used.

For example, the comment

;; foo

would become:

Lexeme::Comment(1, " foo")
§

Dot

A center dot (U+2022), which is used for dotted pairs.

§

ParenClose

An closing parenthesis.

§

ParenOpen

An opening parenthesis.

§

Quote

A single quote.

§

Quasiquote

A backtick.

§

String(Gc<String>)

A string.

§

Symbolish(&'a str)

A symbol or number. The disambiguation is performed when constructing the CST (the Vec<Value>).

§

Unquote(bool)

A comma, possibly followed by an at-sign. The value is true if ,@ was read, false for just ,.
