[pbs-devel] [PATCH v2 backup 0/5] Clippy fixes

[Maximiliano Sandoval]

Differences from v1:

- Rebased on top of master
- Changed prefix to backup
- Added space in commits between description and signed by
- Changed commit descriptions to include the "Why is it bad" blurb instead of
  the URL, with the exception of the self-explanatory cast to i64

Maximiliano Sandoval (5):
  clippy fixes: the borrowed expression implements the required traits
  clippy fixes: use of ok_or followed by a function call
  clippy fixes: casting to the same type is unnecessary
  clippy fixes: Box::new(_) of default value
  clippy fixes: deref which would be done by auto-deref

[pbs-devel] [PATCH v2 backup 1/5] clippy fixes: the borrowed expression implements the required traits

[Maximiliano Sandoval]

Suggests that the receiver of the expression borrows the expression.

[pbs-devel] [PATCH v2 backup 2/5] clippy fixes: use of ok_or followed by a function call

[Maximiliano Sandoval]

The function will always be called. This is only bad if it allocates or does some non-trivial amount of work.
