Struct etherparse::UdpHeader
[−]
[src]
pub struct UdpHeader {
pub source_port: u16,
pub destination_port: u16,
pub length: u16,
pub checksum: u16,
}Udp header according to rfc768.
Fields
source_port: u16
Source port of the packet (optional).
destination_port: u16
Destination port of the packet.
length: u16
Length of the packet (includes the udp header length of 8 bytes).
checksum: u16
The checksum of the packet. The checksum is calculated from a pseudo header, the udp header and the payload. The pseudo header is composed of source and destination address, protocol number
