val sizeof : t -> int

The size of a buffer needed to hold t

val read : Cstruct.t -> (t * Cstruct.t, [ `Msg of string ]) Result.result

Read a t from the given buffer and return it, along with the unused remainder of the buffer. If the buffer cannot be parsed then return an error.

val write : t -> Cstruct.t -> (Cstruct.t, [ `Msg of string ]) Result.result

Write a t into the given buffer. If the buffer is too small, then return an error. Return the unused remainder of the buffer.
