Enum DrainError 

pub enum DrainError {
    Fmt(Error),
    CompoundError(usize),
}

Represents an error which can occur when draining errors from the DiagnosticHandler::drain() and DiagnosticHandler::report_and_drain.

Variants

Fmt(Error)

Defines that the error occured when attempting to write the diagnostic to the output buffer.

CompoundError(usize)

Defines that one-or-more errors were reported during the drain, which are not propogating upwards to the calling function.

The variant defines the number of errors which were reported. Note that this number does not include non-errors such as warnings, nor does it count any sub-diagnostics, such as labels or related errors.

Trait Implementations

impl Debug for DrainError

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

Formats the value using the given formatter.

impl Display for DrainError

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

Formats the value using the given formatter.

impl Error for DrainError

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 DrainError

fn from(err: Error) -> Self

Converts to this type from the input type.
