pub struct DowncastIntoError<'py> { /* private fields */ }
Expand description
Error that indicates a failure to convert a PyAny to a more specific Python type.
Implementations§

impl<'py> DowncastIntoError<'py>
Sourcepub fn new(from: Bound<'py, PyAny>, to: impl Into<Cow<'static, str>>) -> Self
pub fn new(from: Bound<'py, PyAny>, to: impl Into<Cow<'static, str>>) -> Self
Create a new DowncastIntoError
representing a failure to convert the object
from
into the type named in to
.
Sourcepub fn into_inner(self) -> Bound<'py, PyAny>
pub fn into_inner(self) -> Bound<'py, PyAny>
Consumes this DowncastIntoError
and returns the original object, allowing continued
use of it after a failed conversion.
See downcast_into
for an example.
