Documentation
class (Eq c, Num c, Serialize h) => L3Header h a c | h -> a, a -> h, h -> c whereSource
A class of network headers that assumes a checksum is present.
Methods
getChecksum :: h -> cSource
Returns the checksum from the header
setChecksum :: h -> c -> hSource
Sets the checksum in the header
Returns a source for the header.
Returns a destination for the header.
zeroChecksum :: h -> hSource
Returns a header with all the same fields except the checksum is zeroed
computeChecksum :: h -> cSource
Computes the checksum
fillChecksum :: h -> hSource
Computes the checksum, returns a header with the proper checksum
pseudoHeader :: h -> ByteStringSource
Used by various layer 4 protocols (UDP, TCP), a pseudo header is needed to compute the checksum
Returns True iff the checksum is valid
