opwrite declares a file write operations, see the corresponding accessors for the semantics of the various arguments.

tv constructs a bare write operation.
val stamp : t -> stringstamp w is the file write stamp used for caching.
val mode : t -> intint w is the mode of the file written by w.
val file : t -> B0_std.Fpath.tfile w is the file written by w.
data w invokes and discards the write data function. If the write data function raises this is turned into an Error _.
val discard_data : t -> unitdiscard_data w discards the write data function.
