Struct EmptyRecord

Source
pub struct EmptyRecord;
Expand description

A report with no path, relation or attributes

This is convenient both in places where a type is needed as an element for an Empty iterator (as in NotReporting) and to wrap a resource with no further properties in (in a Once iterator, relying on the tree builder to augment the empty path with the actual path).

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
