Trait oracle::oci_attr::data_type::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>

Object Safety

This trait is not object safe.
