Implementations§
source§impl<W, D> Writer<W, D>
impl<W, D> Writer<W, D>
sourcepub fn new(writer: W, operation: D) -> Self
pub fn new(writer: W, operation: D) -> Self
Creates a new Writer
.
All output from the given operation will be forwarded to writer
.
sourcepub fn finish(&mut self) -> Result<()>
pub fn finish(&mut self) -> Result<()>
Ends the stream.
This must be called after all data has been written to finish the stream.
If you forget to call this and just drop the Writer
, you will have
an incomplete output.
Keep calling it until it returns Ok(())
, then don’t call it again.
sourcepub fn into_inner(self) -> (W, D)
pub fn into_inner(self) -> (W, D)
Return the wrapped Writer
and Operation
.
Careful: if you call this before calling Writer::finish()
, the
output may be incomplete.
sourcepub fn writer_mut(&mut self) -> &mut W
pub fn writer_mut(&mut self) -> &mut W
Gives a mutable reference to the inner writer.
sourcepub fn operation_mut(&mut self) -> &mut D
pub fn operation_mut(&mut self) -> &mut D
Gives a mutable reference to the inner operation.
