pub const MAX_KEY_LENGTH: usize = didbot_identity::MAX_DID_LENGTH; // 2_048usizeExpand description
The longest key that gets a bucket of its own.
caller_key answers an address, but a limiter keyed on something the
caller sends is handed an arbitrary string by an unauthenticated
caller. MAX_DID_LENGTH is the
longest an atproto identifier can be at all: a handle caps at 253 bytes
and a DID at this, so nothing longer than this resolves to an account on
any deployment. Keys past it are therefore not identifiers being checked,
and giving each one a bucket would mean retaining a caller-chosen string
per request in a map with no other bound on it.
