Struct MembershipQueryType 

pub struct MembershipQueryType {
    pub max_response_time: u8,
    pub group_address: GroupAddress,
}

IGMPv1/IGMPv2 Membership Query message type.

IGMPv1 & IGMPv2 can be distinguished via the max_response_time field:

• For IGMPv1 the max_response_time field is set to zero
• For IGMPv2 the max_response_time field is set to NOT zero

Fields

max_response_time: u8

The maximum response time for the membership report (only for IGMPv2, set to 0 for IGMPv1).

Specifies the maximum allowed time before sending a responding report in units of 1/10 second.

For IGMPv1, this field is always set to zero.

group_address: GroupAddress

The group address being queried.

Set to zero for general queries, to learn which groups have members on an attached network. Filled for group-specific queries to learn if a particular group has members on an attached network.

For IGMPv1, this field is always set to zero.
