Struct ErrorCode 

pub struct ErrorCode(/* private fields */);

A fault’s code, as the layer that reported it numbers it: its meaning is the IoFault’s source’s (DI-D-50). The Windows backend’s are HRESULTs, the form the I/O ring reports every failure in. A Win32 code is wrapped into one, and read back out of one, by win-durable-ioring, which owns that rule; this type carries the number and does not interpret it.

Carried by every IoFault a layer reports with one, so a consumer reads a code without that layer’s own error types. The Windows backend’s are read from an io::Error by win-durable-ioring’s error_code_of.

use durable_ioring::ErrorCode;

// ERROR_IO_DEVICE, wrapped as an HRESULT.
let code = ErrorCode::from_hresult(0x8007_045D_u32.cast_signed());
assert_eq!(code.hresult().cast_unsigned(), 0x8007_045D);
assert_eq!(code.to_string(), "0x8007045D");
