pub struct OsError { /* private fields */ }

A failed operating system call, such as allocating or protecting memory or suspending a thread.

Carries a short description of the operation and, when available, the raw OS error code.

Implementations

impl OsError

pub fn raw_os_error(&self) -> Option<i32>

Returns the operating system error code (GetLastError on Windows), if one was recorded.

Trait Implementations

impl Clone for OsError

fn clone(&self) -> OsError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OsError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for OsError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for OsError

impl Error for OsError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for OsError

fn eq(&self, other: &OsError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
