Module text 

Presentation-format (zone-file text) helpers shared by Display implementations: escaping (RFC 1035 §5.1), hex, base64 and base32hex (RFC 4648), and the generic RDATA form of RFC 3597 §5.

Record-data Display impls should use these rather than rolling their own, so every type escapes and encodes identically.

Structs

Base64

Display adapter: standard base64 with padding (RFC 4648 §4), as used by DNSKEY, RRSIG, CERT, OPENPGPKEY, DHCID, …

Base32Hex

Display adapter: base32 with the “extended hex” alphabet, uppercase, unpadded (RFC 4648 §7), as used by NSEC3 (RFC 5155 §3.3).

Hex

Display adapter: uppercase hexadecimal, no separators.

Functions

fmt_generic_rdata

Writes RDATA in the generic RFC 3597 §5 form: \# <length> <hex> (just \# 0 when empty).

fmt_label

Writes a label in presentation format: ., \, ", (, ), ;, @ and $ are backslash-escaped; space and non-printable bytes become \DDD (RFC 1035 §5.1, RFC 4343 §2.1).

fmt_quoted

Writes a <character-string> in quoted presentation format: " and \ are backslash-escaped; non-printable bytes become \DDD (RFC 1035 §5.1).
