write
declares a file write operations, see the corresponding accessors for the semantics of the various arguments.
val make :
stamp:string ->
mode:int ->
file:B0_std.Fpath.t ->
data:(unit -> (string, string) Stdlib.result) ->
t
make
constructs a bare write operation.
val stamp : t -> string
stamp w
is the file write stamp used for caching.
val mode : t -> int
int w
is the mode of the file written by w
.
val file : t -> B0_std.Fpath.t
file w
is the file written by w
.
val data : t -> (string, string) Stdlib.result
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 -> unit
discard_data w
discards the write data function.
