Type Aliases

AuthEvents

Tuned auth_events vector. Average events have three auth events. It is debatable whether this could be an ArrayVec but the realistic upper-bound is too high and non-deterministic in the era of restricted-type rooms.

Content

Tuned content buffer. This was chosen empirically based on a significantly high-rate modality in the 96-112B size class reported by jemalloc. With two additional words (hopefully) for the SmallVec it puts us squarely at 128B.

PrevEvents

Tuned prev_events vector. Most events have one prev_event. Many events have more but allocations for all of those cases still beats allocations for all cases.
