Catch returns err if calling work panics with Error{err}, otherwise it returns nil.

Catch1 returns _, err if calling work panics with Error{err}, otherwise it returns t, nil.

Catch2 returns _, _, err if calling work panics with Error{err}, otherwise it returns t1, t2, nil.

Catch4 returns _, _, err if calling work panics with Error{err}, otherwise it returns t1, t2, t3, nil.

Catch4 returns _, _, _, err if calling work panics with Error{err}, otherwise it returns t1, t2, t3, t4 nil.

Fail panics Error{err} if err is not nil, otherwise it panics with an internal error that isn't treated specially by Handle, Catch[N] and Pass.

Fail panics Error{fmt.Errorf(format, args...)}.

Handle, when deferred, recovers Error{err}.

Must calls panic(Error{err}) if err is not nil.

Must1 returns t if err is nil, otherwise it calls panic(Error{err}).

Must2 returns t1, t2 if err is nil, otherwise it calls panic(Error{err}).

Must3 returns t1, t2, t3 if err is nil, otherwise it calls panic(Error{err}).

Must4 returns t1, t2, t3, t4 if err is nil, otherwise it calls panic(Error{err}).

Pass returns r unless it is a check.Error, in which case it re-panics r.

Wrap behaves like Handle, but additionally wraps any returned error in "github.com/go-errors/errors".Error, which provides access to the stack trace.

Error wraps an error.
