Trait FromPyArrow

pub trait FromPyArrow: Sized {
    // Required method
    fn from_pyarrow_bound(value: &Bound<'_, PyAny>) -> Result<Self, PyErr>;
}

Available on crate feature pyarrow only.

Trait for converting Python objects to arrow-rs types.

Required Methods

fn from_pyarrow_bound(value: &Bound<'_, PyAny>) -> Result<Self, PyErr>

Convert a Python object to an arrow-rs type.

Takes a GIL-bound value from Python and returns a result with the arrow-rs type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
