Module sequoia_openpgp::packet::header

OpenPGP packet headers.

An OpenPGP packet header contains packet meta-data. Specifically, it includes the packet’s type (its so-called tag), and the packet’s length.

Decades ago, when OpenPGP was conceived, saving even a few bits was considered important. As such, OpenPGP uses very compact encodings. The encoding schemes have evolved so that there are now two families: the so-called old format, and new format encodings.

Structs

• CTBNew
  A CTB using the new format encoding.
• CTBOld
  A CTB using the old format encoding.
• Header
  A packet’s header.

Enums

• BodyLength
  A packet’s size.
• CTB
  The CTB variants.
• PacketLengthType
  The length encoded for an old style CTB.
