Add threshold variables and values using --argjson (preferred over --arg as we talk about numbers), then extract from the .audits object each item that smashes the corresponding threshold using select, format them in a way to carry the actual value and the threshold to be reused in the output, and finally convert those items into an alert string (which will be output as is due to the --raw-output parameter).

Your code compiles successfully on the current stable release (v1.51). However, TryFrom<_>> for slices (which is what allows you to use try_into()) was only added in rust 1.48, so maybe you are running a rust version older that 1.48. If so, updating to 1.48+ should fix your problem.

stat is a Statvfs structure, the return type of Statvfs::blocks_available() is fsblkcnt_t, and the return type of Statvfs::fragment_size() is c_ulong. These two types are defined in the libc package, which is a paper-thin wrapper around the low-level C OS-calls. The types are equivalent to the C types in the OS-specific *.h files. The sizes of the types vary from platform to platform.

The library you're compiling appears to have some assumptions baked in about these sizes and their arithmetic compatibility.

Some bug reports to the library authors would be in order.

If you're willing to patch the library yourself, then you should first investigate your platform's libc package and check the definitions of all types involved in the errors you're seeing. Then fix the arithmetic expressions so the types are compatible and they don't overflow.

I don't think Rust's type system is smart enough to support one body of code that handles all potential combinations of type sizes both safely (without overflow or truncation) and efficiently (without needlessly casting everything up to u128) . It might be that platform-specific patches are necessary.
