pub const STACK_RECORD_BUDGET_SLOTS: u32 = 64;Expand description
Per-frame stack-record budget (#464 step 2). Counts the number of
Value slots a frame may consume from Vm::stack_record_arena
before further Op::AllocStackRecord requests fall back to the
heap path. 64 slots at the current size_of::<Value>() = 64B
gives ~4 KiB per frame, matching the design-doc proposal in
docs/design/escape-analysis.md. A handler-shaped function
(one outer record of ≤8 fields, plus a handful of small inner
records) fits well inside this without growing.
