Pretty print a token.

Since we only show a single token we can not use diagnostic notation as in the Display impl of Tokenizer. Instead, the following syntax is used:

  • Numeric values and booleans are displayed as in Rust. Floats are always shown in scientific notation.
  • Text strings are displayed in double quotes.
  • Byte strings are displayed in single quotes prefixed with h and hex-encoded, e.g. h'01 02 ef'.
  • An array is displayed as A[n] where n denotes the number of elements. The following n tokens are elements of this array.
  • A map is displayed as M[n] where n denotes the number of pairs. The following n tokens are entries of this map.
  • Tags are displayed with T(t) where t is the tag number.
  • Simple values are displayed as simple(n) where n denotes the numeric value.
  • Indefinite items start with:
    • ?B[ for byte strings,
    • ?S[ for text strings,
    • ?A[ for arrays,
    • ?M[ for maps, and end with ] when a Token::Break is encountered. All tokens in between belong to the indefinite container.
  • Token::Null is displayed as null and Token::Undefined as undefined.
