Enum AsyncValidationError 

pub enum AsyncValidationError {
    Validation(ValidationError),
    Infra(FrameworkError),
}

Errors from AsyncValidator::validate_async.

Separates field-level validation failures (→ redirect-back with old input) from infrastructure failures (→ HTTP 500). A DB error is NEVER a validation result.

Usage

match validator.validate_async().await {
    Ok(()) => { /* proceed */ }
    Err(AsyncValidationError::Validation(e)) => {
        return Err(e.with_old_input(&data).into_action_error("/back"));
    }
    Err(AsyncValidationError::Infra(fe)) => {
        return Err(ActionError::from(fe));
    }
}

Variants

Validation(ValidationError)

One or more field validation rules failed. Use .with_old_input() + redirect_back / redirect_to / into_action_error as usual.

Infra(FrameworkError)

A DB or infrastructure error occurred during an async rule. Propagate as a framework error (→ 500).

Trait Implementations

impl Debug for AsyncValidationError

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

Formats the value using the given formatter.

impl Display for AsyncValidationError

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

Formats the value using the given formatter.

impl Error for AsyncValidationError

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.
