Struct CastIntoError 

pub struct CastIntoError<'py> { /* private fields */ }

Available on crate feature tls only.

Equivalent to CastError for operations where the smart pointer cast transfers ownership of the original object.

The original object can be retrieved using into_inner.

Implementations

impl<'py> CastIntoError<'py>

pub fn new( from: Bound<'py, PyAny>, classinfo: Bound<'py, PyAny>, ) -> CastIntoError<'py>

Create a new CastError representing a failure to interpret a smart pointer to from as a type from the given classinfo.

Equivalent to CastError::new for owned objects.

pub fn into_inner(self) -> Bound<'py, PyAny>

Consumes this CastIntoError and returns the original object, allowing continued use of it after a failed conversion.

See cast_into for an example.

Trait Implementations

impl<'py> Debug for CastIntoError<'py>

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

Formats the value using the given formatter.

impl Display for CastIntoError<'_>

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

Formats the value using the given formatter.

impl Error for CastIntoError<'_>

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<CastIntoError<'_>> for PyErr

Convert CastIntoError to Python TypeError.

fn from(err: CastIntoError<'_>) -> PyErr

Converts to this type from the input type.
