Module counts 

The counts, and the ring each one is kept in.

Structs

Counts

Every count this process holds.

Ring 🔒

A ring of hourly counters, newest at head.

Constants

BUCKETS

Hours in the ring, which is how long a day window is.

HELD

How many counts one Counts holds before it drops the ones that have aged out. A deployment holds far fewer accounts than this; the number is here so a deployment whose accounts come and go cannot grow the map without bound between deletions.

SECONDS_PER_BUCKET 🔒

Seconds in a bucket.

Functions

hour_of

The hour now falls in, in whole hours since the epoch.

index 🔒

Type Aliases

Key 🔒

What one count is kept under: the statement, and the account when the statement counts each account on its own.
