Enum CatchError 

#[non_exhaustive]
pub enum CatchError {
    Bailout,
    NullPanicPtr,
    Panic(String),
}

Error returned when the engine did not run the closure to completion.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Bailout

The engine bailed out, unwinding past the closure.

NullPanicPtr

The closure result was never written back.

Panic(String)

The closure panicked. Holds the panic message; the frames inside the closure have already been unwound and their destructors run.

Trait Implementations

impl Debug for CatchError

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

Formats the value using the given formatter.

impl Display for CatchError

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

Formats the value using the given formatter.

impl Error for CatchError

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<CatchError> for Error

fn from(source: CatchError) -> Self

Converts to this type from the input type.
