Enum sequoia_openpgp::packet::header::PacketLengthType

source ·
pub enum PacketLengthType {
    OneOctet,
    TwoOctets,
    FourOctets,
    Indeterminate,
}
Expand description

The length encoded for an old style CTB.

The PacketLengthType is only part of the old CTB, and is partially used to determine the packet’s size.

See Section 4.2.1 of RFC 4880 for more details.

Variants§

§

OneOctet

A one-octet Body Length header encodes a length of 0 to 191 octets.

The header is 2 octets long. It contains the one byte CTB followed by the one octet length.

§

TwoOctets

A two-octet Body Length header encodes a length of 192 to 8383 octets.

The header is 3 octets long. It contains the one byte CTB followed by the two octet length.

§

FourOctets

A four-octet Body Length.

The header is 5 octets long. It contains the one byte CTB followed by the four octet length.

§

Indeterminate

The packet is of indeterminate length.

Neither the packet header nor the packet itself contain any information about the length. The end of the packet is clear from the context, e.g., EOF.
