Module packet_formats::igmp

Parsing and serialization of Internet Group Management Protocol (IGMP) packets.

This module supports both IGMPv2 and IGMPv3.

The IGMPv2 packet format is defined in RFC 2236 Section 2, and the IGMPv3 packet format is defined in RFC 3376 Section 4.

Modules

• messages
  Implementation of IGMP Messages.

Structs

• HeaderPrefix
  HeaderPrefix represents the first 4 octets of every IGMP message.
• IgmpMessage
  An IGMP message.
• IgmpPacketBuilder
  A builder for IGMP packets.
• IgmpResponseTimeV2
  Thin wrapper around u8 that provides maximum response time parsing for IGMP v2.
• IgmpResponseTimeV3
  Thin wrapper around u8 that provides maximum response time parsing for IGMP v3.

Enums

• IgmpError
  IGMP-specific errors.

Traits

• IgmpMaxRespCode
  Trait for treating the max_resp_code field of HeaderPrefix.
• IgmpNonEmptyBody
  A marker trait for implementers of MessageType. Only MessageTypes whose VariableBody implements IgmpNonEmptyBody (or is () for empty bodies) can be built using IgmpPacketBuilder.
• MessageType
  Trait specifying serialization behavior for IGMP messages.

Functions

• make_v3_possible_floating_point
  Makes an u8 code out of an u32 value that can be represented as a floating point.
• parse_v3_possible_floating_point
  Parses a code that may be representing a floating point value.
• peek_message_type
  Peek at an IGMP header to see what message type is present.
