Win32Error

Struct Win32Error 

Source
pub struct Win32Error(/* private fields */);
Expand description

A raw Win32 error code, kept in the currency it arrived in.

Every failing API this crate calls is a classic last-error API, so a code is always a WIN32_ERROR rather than an HRESULT. Keeping the raw value beside the crate’s own classification means a caller can act on either.

Implementations§

Source§

impl Win32Error

Source

pub const fn from_code(code: u32) -> Self

Wrap a raw WIN32_ERROR.

Source

pub fn from_io(error: &Error) -> Self

Take the code from an OS error, or 0 if it carries none.

A last-error API always sets one, so 0 covers only a fabricated io::Error with no OS error behind it.

Source

pub const fn code(self) -> u32

The raw WIN32_ERROR value.

Source

pub fn to_io_error(self) -> Error

The same failure as a standard io::Error, for callers that funnel everything through std::io.
