2025-02-25rust: add module to convert between success/-errno and io::ResultPaolo Bonzini1-0/+28
It is a common convention in QEMU to return a positive value in case of success, and a negated errno value in case of error. Unfortunately, using errno portably in Rust is a bit complicated; on Unix the errno values are supported natively by io::Error, but on Windows they are not; so, use the libc crate. This is a set of utility functions that are used by both chardev and block layer bindings. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2025-01-10rust: add a utility module for compile-time type checksPaolo Bonzini1-0/+90
It is relatively common in the low-level qemu_api code to assert that a field of a struct has a specific type; for example, it can be used to ensure that the fields match what the qemu_api and C code expects for safety.
