Expand description
Fixed-capacity storage; nothing built on the kernel needs an allocator.
Bridge navigation computers are often heapless microcontrollers, and everything the navigation crates store has a natural bound (swing nodes every few degrees, a few dozen waypoints, a short error excerpt): fixed capacity, checked on insertion.
Public so that aggregates in kinavis (deviation table, route) and adapters
with the same constraint share it.
No unsafe: Inline holds a fully initialised array and a live length;
the unused tail is never visible through Inline::as_slice.
