Enum ErrorKind 

#[non_exhaustive]
pub enum ErrorKind {
    AlreadyExists,
    BrokenPipe,

}

Mirrors std::io::ErrorKind for the variants this crate actually constructs. Kept in alphabetical order so additions stay easy to spot.

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.

AlreadyExists

Entity (file, directory, key, etc.) already exists.

BrokenPipe

Broken pipe — the other end of a stream is closed.

CrossesDevices

Operation attempted across distinct devices/filesystems.

Interrupted

Operation was interrupted (EINTR-equivalent); usually retriable.

InvalidData

Data being read does not match the expected format/schema.

InvalidInput

A function argument had an invalid value.

NotFound

Entity was not found.

Other

Catch-all for errors that don’t fit any other variant.

PermissionDenied

Operation denied due to lack of permissions.

UnexpectedEof

Reader hit end-of-file before satisfying the request.

Unsupported

Operation is not supported on this platform / backend / build.

WouldBlock

Operation would block (EAGAIN / EWOULDBLOCK-equivalent); the caller can retry. Mirrors std::io::ErrorKind::WouldBlock.

WriteZero

write returned Ok(0) while bytes still needed to be written. Mirrors std::io::ErrorKind::WriteZero so callers can distinguish a stuck-writer short write from a generic Other failure.

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> ErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ErrorKind

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl Eq for ErrorKind

impl From<ErrorKind> for Error

fn from(kind: ErrorKind) -> Self

Converts to this type from the input type.

impl PartialEq for ErrorKind

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