Base64Digit

public struct Base64Digit : Hashable
extension Base64Digit: RawRepresentable
extension Base64Digit: Comparable
extension Base64Digit: LosslessStringConvertible

A digit in base 64.

The textual description of a Base64Digit is a single printable ASCII character, determined with the following table:

┌────────────────────────────────────────────────────────┐
| 00 ... 09 | \u{0030} ... \u{0039} | decimal digits     |
| 10 ... 35 | \u{0061} ... \u{007a} | lower case letters |
| 36 ... 61 | \u{0041} ... \u{005a} | upper case letters |
| 62        | \u{002e}              | period             |
| 63        | \u{005f}              | underscore         |
└────────────────────────────────────────────────────────┘

This character set is suitable for use in LLVM assembly identifiers.
