Enum cqrs_es::AggregateError

pub enum AggregateError {
    UserError(UserErrorPayload),
    TechnicalError(String),
}

The base error for the framework.

Variants

UserError(UserErrorPayload)

The user has made an error, a String value contains a message to be delivered to the user.

TechnicalError(String)

A technical error was encountered that prevented the command from being applied to the aggregate. In general the accompanying message should be logged for investigation rather than returned to the user.

Methods

impl AggregateError

pub fn new(msg: &str) -> Self

Convenience function to construct a simple UserError from a &str.

Trait Implementations

impl Debug for AggregateError

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

Formats the value using the given formatter.

impl Display for AggregateError

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

Formats the value using the given formatter.

impl Error for AggregateError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for AggregateError

fn from(err: Error) -> Self

Performs the conversion.

impl PartialEq<AggregateError> for AggregateError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
