Struct CreditRegistrationError 

pub struct CreditRegistrationError {
    error_type: <CreditRegistrationError as BackendError>::ErrorType,
    message: String,
    source: Option<Error>,
    span_trace: Box<SpanTrace>,
    backtrace: Box<Backtrace>,
    location: Option<&'static Location<'static>>,
}

Why a credit registration phase iteration, or a controller calling into one, could not finish. A database failure mid-iteration is one; nothing Suotar answers is. For a models failure, Self::into_model_error recovers the ModelError.

Fields

error_type: <CreditRegistrationError as BackendError>::ErrorType

message: String

source: Option<Error>

span_trace: Box<SpanTrace>

backtrace: Box<Backtrace>

location: Option<&'static Location<'static>>

Implementations

impl CreditRegistrationError

fn render_clean_error(&self, out: &mut dyn Write, color: ColorChoice) -> Result

pub fn clean_string(&self, color: ColorChoice) -> String

Render this error in the clean developer format.

impl CreditRegistrationError

pub fn into_model_error(self) -> Result<ModelError, Self>

Unwraps a CreditRegistrationErrorType::Model error into its ModelError, so a controller maps it as it maps any other, and a missing course still answers 404. Any other error is handed back unchanged.

pub fn cause_chain(&self) -> String

The message and every cause under it, joined with : , for a plain-text record such as a phase’s last error. A cause whose text is already in the chain is left out, since each wrapper’s message repeats the error it wraps.

pub fn is_db_disconnect(&self) -> bool

Whether the database connection was lost anywhere in the cause chain; see is_db_disconnect.

Trait Implementations

impl BackendError for CreditRegistrationError

type ErrorType = CreditRegistrationErrorType

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

fn error_type(&self) -> &Self::ErrorType

fn message(&self) -> &str

fn span_trace(&self) -> &SpanTrace

fn location(&self) -> Option<&'static Location<'static>>

Source location where the error was raised, if captured.

fn new_with_traces_and_location<M: Into<String>, S: Into<Option<Error>>>( error_type: Self::ErrorType, message: M, source_error: S, backtrace: Backtrace, span_trace: SpanTrace, location: Option<&'static Location<'static>>, ) -> Self

The one required constructor; the others delegate to it.

fn new<M, S>(error_type: Self::ErrorType, message: M, source_error: S) -> Self

where M: Into<String>, S: Into<Option<Error>>, Self: Sized,

Create an error, capturing the caller’s location, a backtrace and the span trace.

fn new_with_traces<M, S>( error_type: Self::ErrorType, message: M, source_error: S, backtrace: Backtrace, span_trace: SpanTrace, ) -> Self

where M: Into<String>, S: Into<Option<Error>>, Self: Sized,

Like new but with an explicit backtrace and span trace, e.g. to preserve a source error’s traces.

fn to_different_error<T>( self, new_error_type: <T as BackendError>::ErrorType, new_message: String, ) -> T

where T: BackendError, Self: Sized + 'static + Send,

impl Debug for CreditRegistrationError

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

Formats the value using the given formatter.

impl Display for CreditRegistrationError

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

Formats the value using the given formatter.

impl Error for CreditRegistrationError

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

Returns the lower-level source of this error, if any.

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

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()
