Struct mapped_file::err::WrappedOSError

pub struct WrappedOSError<E: ?Sized>(_, _);

Wraps a piece of context over an OS error

Implementations

impl<E: ?Sized> WrappedOSError<E>

pub fn error(&self) -> &Error

pub fn raw_error(&self) -> c_int

pub fn context(&self) -> &E

Trait Implementations

impl<E: ?Sized> Debug for WrappedOSError<E>where
    E: Display,

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

Formats the value using the given formatter.

impl<E: ?Sized> Display for WrappedOSError<E>where
    E: Debug,

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

Formats the value using the given formatter.

impl<E: ?Sized> Error for WrappedOSError<E>where
    WrappedOSError<E>: Display + Debug,

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

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 self, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

impl<E> From<WrappedOSError<E>> for Error

fn from(from: WrappedOSError<E>) -> Self

Converts to this type from the input type.
