DHCPv6 option.

Some option variants may only be encapsulated in sub-option fields of specific options.

Variants

ClientIdentifier(&'a [u8])

Client Identifier

Used to carry a DUID that identifies the client.

ServerIdentifier(&'a [u8])

Server Identifier

Used to carry a DUID that identifies the server.

IaNa(IaNa<'a>)

Identity Association for Non-temporary Addresses

IaTa(IaTa<'a>)

IaAddress(IaAddress<'a>)

OptionRequest(OptionRequest<'a>)

Preference(u8)

Preference

ElapsedTime(u16)

Elapsed Time

The amount of time in hundredths of a second, since the client began its current DHCP transaction.

RelayMessage(&'a [u8])

Relay Message

Carries a DHCP message in a Relay-forward or Relay-reply message.

ServerUnicast(&'a Addr)

RapidCommit

UserClass(&'a [u8])

InterfaceId(&'a [u8])

ReconfigureMessage(MessageType)

ReconfigureAccept

StatusCode(StatusCode, &'a [u8])

Status Code

The status-message is a UTF-8 encoded string that is not null-terminated.

IaPd(IaPd<'a>)

IaPrefix(IaPrefix<'a>)

InformationRefreshTime(u32)

Information Refresh Time

The value u32::MAX is taken to mean “infinity”.

RelayAgentEchoRequest(&'a [u8])

ClientLinkLayerAddress(&'a [u8])

DHCPv6 Client Link-Layer Address

See: RFC6939
