Enum multipart::server::save::SaveResult
[−]
[src]
pub enum SaveResult<Success, Partial> { Full(Success), Partial(Partial, PartialReason), Error(Error), }
The ternary result type used for the SaveBuilder<_>
API.
Variants
Full(Success)
The operation was a total success. Contained is the complete result.
Partial(Partial, PartialReason)
The operation quit partway through. Included is the partial result along with the reason.
Error(Error)
An error occurred at the start of the operation, before anything was done.
Methods
impl<S, P> SaveResult<S, P> where P: Into<S>
[src]
fn okish(self) -> Option<S>
Convert self
to Option<S>
; there may still have been an error.
fn map<T, Map>(self, map: Map) -> SaveResult<T, T> where Map: FnOnce(S) -> T
Map the Full
or Partial
values to a new type, retaining the reason
in the Partial
case.
fn into_opt_both(self) -> (Option<S>, Option<Error>)
Decompose self
to (Option<S>, Option<io::Error>)
fn into_result(self) -> Result<S>
Map self
to an io::Result
, discarding the error in the Partial
case.
fn into_result_strict(self) -> Result<S>
Pessimistic version of into_result()
which will return an error even
for the Partial
case.
Note: Possible Storage Leak
It's generally not a good idea to ignore the Partial
case, as there may still be a
partially written file on-disk. If you're not using a temporary directory
(OS-managed or via TempDir
) then partially written files will remain on-disk until
explicitly removed which could result in excessive disk usage if not monitored closely.
