Due to certain project requirements, a lower version of the crate package is needed, for example, because some higher versions of the package require rustc to be at least rust1.81. If compiling cargo at this time, it will prompt:
Cargo update (target package) @ (version) -- precise ver
But I'm not sure if this target package is compatible with the highest package version of rustc that I want to use
Is there any way here?
Bypassing the requirements of a crate is always "dangerous" since even if the code compiles, it's almost certain the code actually hasn't been tested. If you override the requirements, then it's on you to test the code and "hope" things work as intended.
--ignore-rust-version can be supplied to cargo which will instruct cargo to not enforce any defined MSRVs. [patch] can be used to override a dependency. If what you're asking is to automatically find the highest version of a crate with a compatible MSRV, then I'm afraid I can't help there.

Thanks,but I feel that Rust lacks this version management mechanism for crates.
