Trait Decodable

pub trait Decodable: Sized {
    // Required method
    fn decode_arrow(col: &dyn Array, row_no: usize) -> Result<Self, Error>;
}

Required Methods

fn decode_arrow(col: &dyn Array, row_no: usize) -> Result<Self, Error>

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.
