Too many non-local impl definition for sp :: FieldOffsets in rust nightly 1.81

[wuanzhuan]

There are too many warning when i update rust to nightly1.81(from nightly 1.75)

warning: non-local impl definition, impl blocks should be written at the same level as their item

Thanks for filling an issue.

What version of Slint are you using?
I believe this is already fixed in the master branch.

[wuanzhuan]

slint version is 1.6

[ogoffart]

Actually, the warning comes from the const-field-offset crate, and it should have been fixed in the 0.5.1 version of it in commit aa7360a
Can you try to run cargo update and see if that helps?

[wuanzhuan]

Have already been solved after cargo update. thanks

[ogoffart]

(I believe all the warning were fixed as part of #4706 , so now i updated the Cargo.toml to make sure an old version can't be used)
