}

Status of a working thin pool, i.e, one that does not have status Fail Note that this struct is incomplete. It does not contain every value that can be parsed from a data line, as some of those values are of unknown format.

Fields

transaction_id: u64

summary: ThinPoolStatusSummary

A summary of some other status information.
