Implementations

impl ProcedureError

pub fn with_context(self, procedure: Fragment) -> Error

Attach procedure name context to Wrapped errors. Named variants already carry the procedure name and convert normally. Wrapped variants become PROCEDURE_003 with the inner error as cause.

Trait Implementations

impl Debug for ProcedureError

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

Formats the value using the given formatter.

impl Display for ProcedureError

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

Formats the value using the given formatter.

impl Error for ProcedureError

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 ProcedureError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<ProcedureError> for Error

fn from(err: ProcedureError) -> Self

Converts to this type from the input type.

impl From<TypeError> for ProcedureError

fn from(err: TypeError) -> Self

Converts to this type from the input type.

impl IntoDiagnostic for ProcedureError

fn into_diagnostic(self) -> Diagnostic

Convert self into a Diagnostic with error code, message, fragment, and other metadata.
