Struct KernelError

pub struct KernelError { /* private fields */ }

Type that represents an error understood by the kernel.

Implementations

impl KernelError

pub fn from_errno(errno: Errno) -> KernelError

Constructs a new error given a raw errno code.

pub fn errno_as_i32(&self) -> i32

Obtains the errno code contained in this error as an integer.

Trait Implementations

impl Debug for KernelError

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

Formats the value using the given formatter.

impl Display for KernelError

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

Formats the value using the given formatter.

impl Fail for KernelError

fn name(&self) -> Option<&str>

Returns the “name” of the error.

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

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn context<D>(self, context: D) -> Context<D>

where D: Display + Send + Sync + 'static, Self: Sized,

Provides context for this failure.

fn compat(self) -> Compat<Self>

where Self: Sized,

Wraps this failure in a compatibility wrapper that implements std::error::Error.

impl From<Error> for KernelError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<Error> for KernelError
