Trait DataType

pub unsafe trait DataType {
    type Type: ToOwned + ?Sized;

    // Required methods
    unsafe fn set(attr: &mut AttrValue, val: &Self::Type) -> Result<()>;
    unsafe fn get(attr: AttrValue) -> Result<<Self::Type as ToOwned>::Owned>;
}

A trait to get and set OCI attributes as rust types. You have no need to use this except implementing OciAttr for your type.

Required Associated Types

type Type: ToOwned + ?Sized

Required Methods

unsafe fn set(attr: &mut AttrValue, val: &Self::Type) -> Result<()>

unsafe fn get(attr: AttrValue) -> Result<<Self::Type as ToOwned>::Owned>

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.
