Struct flex_error::ErrorReport

pub struct ErrorReport<Detail, Trace> {
    pub detail: Detail,
    pub trace: Trace,
}

An ErrorSource that provides both the error detail and error trace separately. The error trace in an error report also already contains the trace of the current error detail already. so new errors that arise from an ErrorReport only need to access the trace object to add new traces to it.

ErrorReport should be used for all application code that uses flex-error. When defining new error types using define_error!, the error name is defined as a type alias to ErrorReport.

Fields

detail: Detail

trace: Trace

Implementations

impl<Detail, Trace> ErrorReport<Detail, Trace>

pub fn trace_from<E, Cont>(source: E::Source, cont: Cont) -> Self where
    Detail: Display,

Formats the value using the given formatter.

impl<Detail, Trace> Display for ErrorReport<Detail, Trace> where
    Trace: Display, 

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

Formats the value using the given formatter.

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()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<Detail, Trace> ErrorSource<Trace> for ErrorReport<Detail, Trace>

type Source = Self

The type of the error source.

type Detail = Detail

The type of the error detail that can be extracted from the error source

fn error_details(source: Self::Source) -> (Self::Detail, Option<Trace>)

Extracts the error details out from the error source, together with an optional error trace.
