Affected versions allow arbitrary caller-provided code to execute before the lifetime of main
.
If the caller-provided code accesses particular pieces of the standard library that require an initialized Rust runtime, such as std::io
or std::thread
, these may not behave as documented. Panics are likely; UB is possible.
The flaw was corrected by enforcing that only code written within the inventory
crate, which is guaranteed not to access runtime-dependent parts of the standard library, runs before main
. Caller-provided code is restricted to running at compile time.
