There are a number of places where we generate random Durations
in a range which starts at zero.
These call sites currently (i) have to write out Duration::ZERO
or equivalent, and (ii) would have to use gen_range_checked and expect
the result, even though it can be statically proven to be OK.
To make this slightly smoother, provide `GenRangeInfallible` and
`gen_range_infallible`.
Ideally we would be allowed to use vanilla gen_range() here, but there
doesn't seem to be a way to allow a specific clippy-forbidden method
using #[allow] and we probably don't want to make a blanket allow.
This launders the closure so that clippy's
clippy::redundant_closure_call can't see it.
We can't have a local #[allow] because it would be on an expression,
which isn't allowed on stable.
This avoids having to use more clumsy idioms at call sites.
This is a perf issue, only. If tests are too slow, we will notice and
ca speed them up. We should optimise for clarity and convenience,
rather than speed.
Forbidding this can result in churn between vec![] and [] as tests are
updated and changed.
Rationale: no-one writes these by default without thinkinh. If they
are unnecessary, then either the string must have had " in it
before (in which case it might do again), or it is near other strings
which *do* need it.
And having it does no harm; indeed IMO it can increase clarity.
Alternative to !1388's
Fix new "needless_raw_string_hashes" lint from clippy +nightly
Originally they didn't check err.kind(), since err.kind() can never
increase their severity. We lost that behavior with !1386, and we
became dependent on it with arti!1383. Since they both merged at
the same time, CI broke.
This patch restores their original behavior.
This abolishes some quintuplication.
The output is identical except that:
* The syntax display in the rustdoc output for the resulting macros
seems to have somewhat less whitepsace.
* The whimsical error messages in the examples are all identical.
Ah well.
I identified the cases to replace by searching for the string
`.report()`. There are a few that I didn't change:
* A couple of cases that used anyhow::Error,
* One case that reported two Errors.
* Two cases in `tor_hsclient::err` that just did
`error!("Bug: {}")`.
I have also not audited the cases in `tor-hsclient` where we're using
`tor_error::Report` manually.
Nonetheless, closes#949.
Many of these call sites would panic if, somehow, the upper bound was
zero. In most cases it is very complicated to see if whether this
could happen.
However, there is a better answer:
Durations are (conceptually) dense, so picking the closed set (which
includes its boundary) rather than the open one (which doesn't) will
make little practical difference.
So change four call sites to use `..=` instead of just `..`.
The main contribution here is a set of convenience macros for
logging error `Report`s. Notably, this macros always logs
`Internal` and `BadAspiUsage` errors at `WARN`, unless they
are already at `ERROR` or more.
This is a little tricky because `tracing::event!()` requires
its Level argument to be a constant.
