Enum Token 

pub enum Token {
    Operator(Operator),
    InvalidOperator(u8),
    InvalidTwoByteOperator(u8),
    Operand(Number, Option<BcdComponents>),
}

Either a PostScript DICT operator or a (numeric) operand.

Variants

Operator(Operator)

An operator parsed from a DICT.

InvalidOperator(u8)

An opcode that is not a known operator.

Reported rather than refused: a DICT containing one is still a DICT, and what to do about it is the caller’s decision. FreeType ignores unknown operators and clears the stack, which is what entries does; refusing here would leave a caller no way to do the same through the raw view.

InvalidTwoByteOperator(u8)

As InvalidOperator, for the two-byte form.

Carries the extended opcode only; the byte before it is always the escape.

Operand(Number, Option<BcdComponents>)

A number parsed from a DICT. If the source was in binary coded decimal format, then the second field contains the parsed components.
