An abstract interface which when implemented provides an interface to write bytes from an array buffer to a file/resource asynchronously.
p.byteLength bytes from
p to the underlying data stream. It
resolves to the number of bytes written from
p.byteLength) or reject with the error encountered that caused the
write to stop early.
write() must reject with a non-null error if
would resolve to
write() must not modify the
slice data, even temporarily.
Implementations should not retain a reference to
