Struct Errno 

pub struct Errno {
    pub code: ErrnoCode,
    /* private fields */
}

Fields

code: ErrnoCode

Implementations

impl Errno

pub fn new(code: ErrnoCode) -> Self

Creates a new Errno with the given ErrnoCode and the location of the caller.

Callers should use the errno! macro instead of calling this function directly.

pub fn with_context(code: ErrnoCode, context: impl ToString) -> Self

pub fn return_value(&self) -> u64

pub fn is_restartable(&self) -> bool

Returns whether this Errno indicates that a restartable syscall was interrupted.

Trait Implementations

impl Clone for Errno

fn clone(&self) -> Errno

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Errno

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

Formats the value using the given formatter.

impl Display for Errno

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

Formats the value using the given formatter.

impl Error for Errno

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<Errno> for Status

fn from(e: Errno) -> Self

Converts to this type from the input type.

impl PartialEq<ErrnoCode> for Errno

fn eq(&self, other: &ErrnoCode) -> 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.
