Enum ErrorKind 

#[non_exhaustive]
pub enum ErrorKind {
    InvalidArgument,
    NotFound,
    AlreadyExists,
    Io,
    Storage,
    Migration,
    Conflict,
    AmbiguousResolution,
    Fingerprint,
    Unsupported,
    Internal,
}

Stable categories shared by core services and external adapters.

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.

InvalidArgument

A caller supplied invalid input.

NotFound

A requested domain object does not exist.

AlreadyExists

An object or relationship already exists.

Io

An operating-system I/O operation failed.

Storage

A persistence backend failed.

Migration

A schema migration failed.

Conflict

Current state conflicts with the requested operation.

AmbiguousResolution

Media resolution produced multiple credible candidates.

Fingerprint

Media fingerprint calculation or validation failed.

Unsupported

The requested operation is not supported.

Internal

An internal domain invariant was violated.

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 Eq for ErrorKind

impl Hash for ErrorKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
