impl Lookup

Source

pub fn builder() -> LookupBuilder<((), (), (), (), ())>

Create a builder for building Lookup. On the builder, call .attributes(...), .inode(...), .generation(...)(optional), .attr_timeout(...)(optional), .entry_timeout(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of Lookup.
