feature=[dep:xxx]

[miaomiao1992]

the package my_project depends on cratexxx, with features: featurexxx but cratexxx does not have these features.
It has an optional dependency with that name, but that dependency uses the "dep:" syntax in the features table, so it does not have an implicit feature with that name.

failed to select a version for my_project which could resolve this conflict

maybe we can get dependencies by parsing Cargo.lock ?
