NotAvailable

io_uring not available on this platform.

FdNotRegistered(i32)

File descriptor not registered.

Implementations

impl IoUringError

pub fn from_errno(message: impl Into<String>, errno: i32) -> Self

Create an operation failed error from an error code.

pub const fn is_fatal(&self) -> bool

Check if this error indicates the ring should be recreated.

pub const fn is_transient(&self) -> bool

Check if this error indicates a transient condition.

Trait Implementations

impl Debug for IoUringError

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

Formats the value using the given formatter.

impl Display for IoUringError

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

Formats the value using the given formatter.

impl Error for IoUringError

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<IoUringError> for Error

fn from(source: IoUringError) -> Self

Converts to this type from the input type.
