Portable error classification. This is a superset of embedded_io::ErrorKind and retains the std::io conditions Hadris needs for helper operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotFound

An entity was not found.

PermissionDenied

An operation lacked sufficient permissions.

ConnectionRefused

A connection attempt was refused.

ConnectionReset

A connection was reset by its peer.

ConnectionAborted

A connection was aborted locally.

NotConnected

The endpoint is not connected.

AddrInUse

The requested address is already in use.

AddrNotAvailable

The requested address is unavailable.

BrokenPipe

A write targeted a closed pipe or connection.

AlreadyExists

An entity already exists.

WouldBlock

The operation would block.

InvalidInput

An input parameter was invalid.

InvalidData

Input data was malformed.

TimedOut

The operation timed out.

WriteZero

A write produced no progress.

Interrupted

The operation was interrupted and may be retried.

UnexpectedEof

Input ended before the requested data was read.

Unsupported

The requested operation is unsupported.

OutOfMemory

The operation could not allocate required memory.

Other

An error without a more specific portable classification.

Implementations

impl ErrorKind

pub const fn kind(&self) -> Self

impl Eq for ErrorKind

impl Error for ErrorKind

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
