Enum StorageIoError 

pub enum StorageIoError {
    QueueFull,
    Io(Error),
    BadFd(IoFd),
    Closed,
    BufferExhausted,
}

Errors from the storage I/O layer.

Intentionally small — this is used on the hot path.

Variants

QueueFull

The submission queue or internal buffer is full.

Io(Error)

An OS-level I/O error occurred.

BadFd(IoFd)

The requested IoFd is not registered.

Closed

The backend is closed / shutting down.

BufferExhausted

Buffer pool exhausted (io_uring only).

Trait Implementations

impl Debug for StorageIoError

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

Formats the value using the given formatter.

impl Display for StorageIoError

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

Formats the value using the given formatter.

impl Error for StorageIoError

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 StorageIoError

fn from(e: Error) -> Self

Converts to this type from the input type.
