A B/IPv6 BVLL message could not be decoded or encoded.

The variants mirror BvllError’s, for Annex U’s type octet, address length and functions; B/IPv6 messages carry no tables. Each one names the direction it comes from. None of them allocates, so the type is Copy. Later releases may add variants, so a match outside this crate needs a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TooShort

Decode: the datagram is shorter than the 4-octet BVLL header.

Fields

length: usize

Octets in the datagram.

NotBip6

Decode: the BVLC Type octet is not 0x82, so the datagram is not a B/IPv6 BVLL message (Annex U.2).

Fields

bvlc_type: u8

The type octet received.

LengthMismatch

Decode: the Length field disagrees with the datagram. It counts the whole message, header included (Annex U.2), so a datagram cut short and one with octets after the message both fail here.

Fields

declared: usize

Length the header declares.

received: usize

Octets in the datagram.

UnknownFunction

Decode: a function code Annex U.2 doesn’t define, so its payload has no known layout.

Fields

function: u8

The function octet.

PayloadLength

Decode: the payload doesn’t fit its function’s layout (see Bvlc6Function::payload_shape).

Fields

function: Bvlc6Function

The message’s function.

length: usize

Octets after the header.

AddressLength

A B/IPv6 address that is not 18 octets long (Annex U.1.1.2).

Fields

length: usize

Octets supplied.

TooLong

Encode: the message is longer than its 16-bit Length field can state.

Fields

length: usize

Octets the message would take.

UndefinedResultCode

Encode: a BVLC-Result whose code Annex U.2.1.1 doesn’t define.

Fields

code: u16

The code supplied.

BufferExhausted

Encode: the sink has no room for the message. Nothing was written to a sink with a fixed capacity.

Fields

needed: usize

Octets the write needed.

available: usize

Room the sink had.
