Struct SysError

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

Errors associated with a sys errno

Implementations

impl SysError

pub fn new(errno: i32) -> SysError

create SysError from errno

pub fn last() -> SysError

create SysError from last_os_error

pub fn errno(self) -> i32

get internal errno

Trait Implementations

impl Clone for SysError

fn clone(&self) -> SysError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SysError

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

Formats the value using the given formatter.

impl Display for SysError

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

Formats the value using the given formatter.

impl Error for SysError

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 From<Error> for SysError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<SysError> for Error

fn from(err: SysError) -> Error

Converts to this type from the input type.

impl PartialEq for SysError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
