def IO.throwServerError {α : Type} (err : String) : IO α

Equations

• IO.throwServerError err = throw (IO.userError err)

def IO.FS.Stream.chainRight (a : IO.FS.Stream) (b : IO.FS.Stream) (flushEagerly : optParam Bool false) : IO.FS.Stream

Chains two streams by creating a new stream s.t. writing to it just writes to a but reading from it also duplicates the read output into b, c.f. a | tee b on Unix. NB: if a is written to but this stream is never read from, the output will not be duplicated. Use this if you only care about the data that was actually read.
