Trait AnyHandle 

Source 
pub unsafe trait AnyHandle {
    // Required methods
    fn as_handle(&self) -> Handle;
    fn handle_type(&self) -> HandleType;
}
Expand description

Provides access to the raw underlying ODBC handle. This trait is implemented for environment, connection and statement handles. Self::handle_type allows to determine the type of the handle at runtime. Yet, this information is not in the type system. This is useful for operations, which must work with all handle types. E.g. fetching diagnostics.

§Safety

The handle provided by as_handle must be valid and match the type returned by handle_type.

Required Methods§

Source

fn as_handle(&self) -> Handle

The raw underlying ODBC handle used to talk to the ODBC C API. The handle must be valid.

Source

fn handle_type(&self) -> HandleType

The type of the ODBC handle returned by as_handle. This is a method rather than a constant in order to make the type object safe.
