Struct InspectWriter
pub struct InspectWriter<W, F> { /* private fields */ }An adapter that lets you inspect the data that's being written.
This is useful for things like hashing data as it's written out.
Implementations
impl<W, F> InspectWriter<W, F>
fn new(writer: W, f: F) -> InspectWriter<W, F> where W: AsyncWrite, F: FnMut(&[u8]),Create a new
InspectWriter, wrappingwriteand callingffor the data successfully written by each write call.The closure
fwill never be called with an empty slice. A vectored write can result in multiple calls tof- at most one call tofper buffer supplied topoll_write_vectored.fn into_inner(self) -> WConsumes the
InspectWriter, returning the wrapped writer
