pub type PropertiesResult<'err, T, B> = <<B as PropertiesBackend>::DataFilesAvailability as DataFilesAvailability>::Result<'err, T>;Expand description
Wrapper for the return type of SwhGraphProperties methods.
When B implements GuaranteedDataFiles (the most common case), PropertiesResult<'err, T, B>
is exactly the same type as T.
aWhen B implements OptionalDataFiles (which is the case when using
opt_load_* instead of load_* or load_all for example),
then PropertiesResult<'err, T, B> is exactly the same type as Result<T, &'err UnavailableProperty>.
