val into_cstruct :

t ->
Cstruct.t ->
(unit, error) Stdlib.result
into_cstruct ~pseudoheader ~payload t buf
attempts to assemble a UDP header in buf
with t.src_port
and t.dst_port
set, along with the correct length and checksum. It does not write pseudoheader
or payload
into the buffer, but requires them to calculate the correct checksum.
val make_cstruct :
pseudoheader:Cstruct.t ->
payload:Cstruct.t ->
t ->
Cstruct.t
make_cstruct ~pseudoheader ~payload t
allocates, fills, and and returns a buffer representing the UDP header corresponding to t
. make_cstruct
will allocate 8 bytes for the UDP header. payload
and pseudoheader
are not directly represented in the output, and are required for correct computation of the UDP checksum only. The checksum will be properly set to reflect the pseudoheader, header, and payload.
