This class is used together with crate::buffers::BufferDescription to specify the layout of buffers bound to ODBC cursors and statements.

Variants

Text

Text buffer holding strings with binary length of up to max_str_len.

Fields of Text

max_str_len: usize

Maximum string length. Terminating zero is excluded, i.e. memory for it will be implicitly allocated if required.

F64

64 bit floating point

F32

32 bit floating point

Date

Describes a buffer holding crate::sys::Date values.

Time

Describes a buffer holding crate::sys::Time values.

Timestamp

Describes a buffer holding crate::sys::Timestamp values.

I8

Signed 8 Bit integer

I16

Signed 16 Bit integer

I32

Signed 32 Bit integer

I64

Signed 64 Bit integer

U8

Unsigned 8 Bit integer

Bit

Can either be zero or one
