Trait HasData 

pub trait HasData: DataAccess {
    const ACCESS: Access;
}

A DataAccess that can read or write, so that a target can be made from it, and the Access a target made from it states. NoData is not one:

use durable_ioring::{HasData, NoData};

fn needs_data<A: HasData>() {}
needs_data::<NoData>();

use durable_ioring::{Access, HasData, ReadOnly, ReadWrite, WriteOnly};

assert_eq!(ReadOnly::ACCESS, Access::ReadOnly);
assert_eq!(WriteOnly::ACCESS, Access::WriteOnly);
assert_eq!(ReadWrite::ACCESS, Access::ReadWrite);

Required Associated Constants

const ACCESS: Access

What a target made from a handle with this access states.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
