0.12.0 fails to compile: wholesym trait bounds not satisfied

[cdown]

Didn't have time to look into what's going on here yet, but I thought you'd like to know. From cargo install samply:

error: could not compile `samply` (bin "samply") due to 3 previous errors

[cdown]

--locked works, so it seems like then somewhere some versioning or version ranges are not restrictive enough.

[mstange]

Ugh, thanks for reporting! I may need to yank the recent dot release of samply-symbols.

[mstange]

I'm working on this now.

[mstange]

Here's the dependency chains as written down in each released crate's Cargo.toml:

samply 0.12.0 -> wholesym 0.5.0 -> samply-symbols 0.22.0 -> object 0.35
samply 0.12.0 -> wholesym 0.5.0 -> object 0.35

samply-symbols has a public API which expects a type from object.

I recently released samply-symbols 0.22.1 which depends on object 0.36. This was a mistake, because it is a breaking change to the public API debug_id_for_object.
Now wholesym 0.5.0 can no longer pass its object 0.35 types to debug_id_for_object.

I'm planning to release samply-symbols 0.22.2 with the same code as samply-symbols 0.22.0. Then I will yank samply-symbols 0.22.1.

[mstange]

Done. cargo install samply works for me locally again.

[mstange]

cargo semver-checks missed this breaking change, I think that's obi1kenobi/cargo-semver-checks#638 .
