Struct SeqTailRead 

Source 
pub struct SeqTailRead<'a, T: SeqElement> { /* private fields */ }
Expand description

Read guard over a Seq<T> tail acquired through a Context: owns the shared account byte borrow (narrowed to the tail region) and the segment-registry lease, yielding a TailSeq cursor via seq.
