Implementations

impl<'a> BlobParam<'a>

pub fn new(blob: &'a mut impl Blob) -> Self

Trait Implementations

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

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

impl HasDataType for BlobParam<'_>

fn data_type(&self) -> DataType

The SQL data as which the parameter is bound to ODBC.

impl Parameter for &mut BlobParam<'_>

unsafe fn bind_parameter(
    self,
    parameter_number: u16,
    stmt: &mut impl Statement
) -> Result<(), Error>
