Trait Allocate 

pub trait Allocate<'src, SRC: AsSQLHANDLE>: Handle {
    // Required method
    unsafe fn from_raw(output_handle: NonNull<RawHandle>) -> Self;

    // Provided methods
    fn SQLAllocHandle(InputHandle: &'src SRC) -> (Result<Self, ()>, SQLRETURN) { ... }
    fn SQLFreeHandle(self) { ... }
}

Required Methods

unsafe fn from_raw(output_handle: NonNull<RawHandle>) -> Self

Creates handle from a raw pointer

Safety

The given raw pointer must point to a valid handle of the required type

Provided Methods

fn SQLAllocHandle(InputHandle: &'src SRC) -> (Result<Self, ()>, SQLRETURN)

Allocates an environment, connection, statement, or descriptor handle.

For complete documentation on SQLAllocHandle, see API reference.

Returns

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_INVALID_HANDLE, or SQL_ERROR.

fn SQLFreeHandle(self)

Frees resources associated with a specific environment, connection, statement, or descriptor handle.

For complete documentation on SQLFreeHandle, see API reference.

Panics

Panics if the DM returns value other than SQL_SUCCESS

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.
