Implementations

impl ExecError

pub fn with_context( name: impl ToString, line: usize, col: usize, len: usize, error: ExecError, ) -> Self

Wrap an error with location context, preserving the error chain. The innermost (original) error location stays as primary, outer contexts are added to the cause chain.

pub fn as_structured(&self) -> Option<&StructuredError>

Get the structured error if this is one

Trait Implementations

impl Debug for ExecError

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

Formats the value using the given formatter.

impl Display for ExecError

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

Formats the value using the given formatter.

impl Error for ExecError

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 ExecError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ExecError> for TemplateError

fn from(source: ExecError) -> Self

Converts to this type from the input type.

impl From<FuncError> for ExecError

fn from(source: FuncError) -> Self

Converts to this type from the input type.
