pub type RawOsError = i32;🔬This is a nightly-only experimental API. (
raw_os_error_ty #107792)Expand description
The type of raw OS error codes returned by Error::raw_os_error.
This is an i32 on all currently supported platforms, but platforms
added in the future (such as UEFI) may use a different primitive type like
usize. Use asor into conversions where applicable to ensure maximum
portability.
