Struct RxMetadata 

Source 
pub struct RxMetadata<'a> { /* private fields */ }
Expand description

A guard for reading metadata on an Rx buffer.

Holds a shared borrow of the underlying descriptor (DescRef), ensuring that atomic reference counting is performed only once when obtaining and dropping this guard, rather than on every individual field access.

Implementations§
