Module IPv4.WriterSource
Efficient IPv4 payload composition.
A t value represents a payload to be sent in an IPv4 packet. Three constructors are provided depending on whether the data is already in memory as a string, as multiple strings, or should be written directly into the outgoing buffer. The writer handles fragmentation transparently when the payload exceeds the path MTU.
of_string ipv4 str creates a writer that sends str as the payload.
of_strings ipv4 strs creates a writer that sends the concatenation of strs as the payload. This avoids copying the strings into a single buffer.
into ipv4 ~len fn creates a writer that fills the payload by calling fn buf, where buf is a buffer of size len positioned after the IPv4 header. This is the zero-copy path for upper-layer protocols (like UDP's UDP.sendfn) that can write directly into the outgoing frame.
