Trait ToArrow 

pub trait ToArrow {
    type Item;
    type Builder: ArrowBuilder<Self::Item> + ArrayBuilder;

    // Required method
    fn to_datatype() -> DataType;
}

Required Associated Types

type Item

type Builder: ArrowBuilder<Self::Item> + ArrayBuilder

Required Methods

fn to_datatype() -> DataType

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.
