Module check 

Check IDs, severity and the per-page issue bitmask. The check metadata (title, severity, category) lives in the checks crate.

Structs

IssueBits

One bit per check, stored as pages.issues. Bit numbers are never reused.

Enums

CheckId

Every check, with its stable ID. The value is the bit in IssueBits and is never reused; new checks are appended with the next number. The slug is the serde name.

Severity
