The latest release of
once_cell
(1.15.0) bumped their msrv to 1.56.0. Miette didn't previously declare an MSRV, but we have a CI pass that tests against rust 1.54.0. As a result, CI is currently broken.There are a few options here:
once_cell
dependency as<1.15.0
, and continue testing against rust 1.54.0.miette
itselfI don't have strong opinions about which of these options to go for, it's really up to the
miette
maintainers. Happy to switch out this PR for one of the other options if you would prefer.
