• formatWithHint. Creates a fmt function, changing the behaviour of matching fields. Value args follow...

  • <fn> : calls the fn like a format procedure for that field.
  • <ptr> : assumption is a format string, concat and use.
  • .skip : skips and doesn't print the field.
  • .skip_noted : skips printing out the value but still notes the existence of the field. E.g. .field_name = ⋯.
  • .str : Anything string like gets formatted with "{s}".
  • .str_ctrlpic : Like .str but all control chars are replaced with the equivelent from the Unicode Control Pictures Block.
  • .fixed_c_str : C-like string that can be passed to std.mem.sliceTo(str, 0) prior to "{s}".
  • .flags : Prints out enabled fields in a flag struct (struct with just bool s). Skips non bool fields.
  • .unix_time : An int that is convertible into a std.posix.time_t, Print an 8601 like date-time. libc required.
• time8601Format. Prints out a 8601 like time-date from a Linux epoch. [2025年11月12日T17:51:05]. libc required.
• strControlPicturesFormat. Prints string translating control chars to the Control Pictures Block. "␉Hello World␊".
• flagsFormat. Prints out enabled fields in a flag struct (struct with just bool s). Skips non bool fields.
• HexDump. Prints out a formatted hex dump from the provided u8 slice.
• formatWithHintAndFlags. Creates a fmt function, nearly identical to formatWithHint. Any unspecified bool fields be used in the trailing enabled flags indicator. .{ .field_name= *, (A B D) }
