pub const MAX_BTREE_DEPTH: usize = 32;Expand description
Maximum B+tree depth.
At fanout ≥ 4 a 32-level tree holds 2^64 entries, which exceeds
the page-id space. The bound exists so Rule 1 tree
traversals always terminate; a tree that somehow grew past 32
levels surfaces as Error::BTreeDepthExceeded rather than a
stack overflow.
crate link target above is documented as power-of-ten.md
Rule 1: no unbounded recursion.
