pub const DEFAULT_CAPACITY: u32 = 256;Expand description
Default number of slots per ring.
Paired with DEFAULT_SLOT_SIZE so the total default ring memory
is ~4.4 MiB per face (256 × 8960 × 2) — the same budget as the
original v1 design. Tools that need larger Data packets (chunked
producers at 64+ KiB segments) call faces/create with an explicit
mtu, and the router creates a face with a proportionally larger
slot_size and smaller capacity via capacity_for_slot.
