Struct IpV4Filter

#[repr(C, packed(1))]
pub struct IpV4Filter {
    pub valid_fields: IpV4FilterFlags,
    pub src_address: IpAddressV4,
    pub dest_address: IpAddressV4,
    pub protocol: u8,
    pub padding: [u8; 3],
}

Represents an IPv4 filter used by the packet filtering mechanism.

A Rust equivalent for _IP_V4_FILTER.

The valid_fields field specifies which fields in the filter structure are used for filtering. The src_address field contains the source IPv4 address information. The dest_address field contains the destination IPv4 address information. The protocol field represents the IP protocol number. The padding field is used for alignment purposes.

Fields

valid_fields: IpV4FilterFlags

src_address: IpAddressV4

dest_address: IpAddressV4

protocol: u8

padding: [u8; 3]
