Enum RoutineError

        function: Fragment,
        expected: usize,
        actual: usize,
    },
    FunctionInvalidArgumentType {

    Wrapped(Box<Error>),
}

Unified error type for all routines (functions and procedures).

Replaces the previously-separate FunctionError and ProcedureError. Variant names are prefixed (Function* / Procedure*) so the user-visible diagnostic wording can stay distinct, but the field names within each variant follow the legacy convention (function: / procedure:) so the migration from the legacy types only changes the variant name, not the per-variant struct layout.

Implementations

impl RoutineError

pub fn with_context(self, fragment: Fragment, is_procedure: bool) -> Error

Attach routine name context to Wrapped errors.

is_procedure selects whether the wrapped diagnostic uses the FUNCTION_007 or PROCEDURE_003 code so the user-visible wording stays correct.

Trait Implementations

impl Debug for RoutineError

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

Formats the value using the given formatter.

impl Display for RoutineError

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

Formats the value using the given formatter.

impl Error for RoutineError

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.
