Trait pyo3::conversion::PyTryInto

pub trait PyTryInto<T>: Sized {
    // Required methods
    fn try_into(&self) -> Result<&T, PyDowncastError<'_>>;
    fn try_into_exact(&self) -> Result<&T, PyDowncastError<'_>>;
}

👎Deprecated since 0.21.0

Trait implemented by Python object types that allow a checked downcast. This trait is similar to std::convert::TryInto

Required Methods

fn try_into(&self) -> Result<&T, PyDowncastError<'_>>

👎Deprecated since 0.21.0: use value.downcast() instead of value.try_into()

Cast from PyObject to a concrete Python object type.

fn try_into_exact(&self) -> Result<&T, PyDowncastError<'_>>

👎Deprecated since 0.21.0: use value.downcast() instead of value.try_into_exact()

Cast from PyObject to a concrete Python object type. With exact type check.

Object Safety

This trait is not object safe.
