Expand description

A plain old data type. With an associated C Type. Must be completely stack allocated without any external references. In addition to that the buffer size must be known to ODBC in advance.

§Safety

A type implementing this trait, must be a fixed sized type. The information in the C_DATA_TYPE constant must be enough to determine both the size and the buffer length of an Instance.

Required Associated Constants§

Source

const C_DATA_TYPE: CDataType

ODBC C Data type used to bind instances to a statement.

Dyn Compatibility§

This trait is not dyn compatible.

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