Enum CoreError 

pub enum CoreError {
    Validation(String),
    NotFound(String),
    IdentityMismatch(String),
    IllegalTransition(String),
    CommandReuse(String),
    Causal(String),
    Encoding(String),
}

Stable semantic error categories.

Variants

Validation(String)

An object failed semantic validation.

NotFound(String)

A referenced object does not exist.

IdentityMismatch(String)

An immutable identity did not match its content.

IllegalTransition(String)

A state-machine transition is not legal.

CommandReuse(String)

A command ID was reused with different semantics.

Causal(String)

A causal parent is missing or the event graph is cyclic.

Encoding(String)

Canonical encoding failed.

Implementations

impl CoreError

pub const fn code(&self) -> &'static str

Stable machine-readable error code.

Trait Implementations

impl Clone for CoreError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoreError

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

Formats the value using the given formatter.

impl Display for CoreError

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

Formats the value using the given formatter.

impl Eq for CoreError

impl Error for CoreError

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 CoreError

fn from(error: Error) -> Self

Converts to this type from the input type.

impl PartialEq for CoreError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
