Trait odbc_api::handles::DelayedInput

pub unsafe trait DelayedInput {
    fn cdata_type(&self) -> CDataType;
    fn indicator_ptr(&self) -> *const isize;
    fn stream_ptr(&mut self) -> *mut c_void;
}

Stream which can be bound as in input parameter to a statement in order to provide the actual data at statement execution time, rather than preallocated buffers.

Required methods

fn cdata_type(&self) -> CDataType

Then streaming data to the “data source” the driver converts the data from this type.

fn indicator_ptr(&self) -> *const isize

Either odbc_sys::DATA_AT_EXEC or the result of odbc_sys::len_data_at_exec.

fn stream_ptr(&mut self) -> *mut c_void

Pointer to the stream or an application defined value identifying the stream.
