When debugging #868, I noticed that a long version info with commit_hash helps or else I got only cargo-insta 1.46.3 where I'm unsure if the used tool is from a local build.

Note that the branch and commit fields are empty if installed via cargo install cargo-insta because the published crate has no .git info. But that should be fine.

thanks @tisonkun !

do we need a whole new dependency for this? we would need to resolve the MSRV issue...

[tisonkun]

@max-sixty I was also noticing this after seeing the CI failure.

I'm not quite sure about MSRV. Because cargo-insta is a binary rather than a software library that needs to be depended upon. Consequently, I'm unclear on this project's MSRV policy.

I decided to leave it as is for now, but we do need to bump the MSRV to accept this PR.

Seems not shadow-rs's issue but time's issue that used in build-dependencies.

Let me see if I can relax the MSRV requirement.

[tisonkun]

I'm going to see if shadow-rs can depend on jiff but it also requires MSRV >= 1.70.0, while cargo-insta has MSRV=1.66.0.

Pin time can't work because shadow-rs requires time >= 0.3.47 while only time <= 0.3.23 fits MSRV <= 1.66.0.
