Struct odbc_api::parameter::WideText

pub struct WideText;

Intended to be used as a generic argument for VarCell to declare that this buffer is used to hold wide UTF-16 (as opposed to narrow ASCII or UTF-8) text. Use this to annotate [u16] buffers.

Trait Implementations

impl Clone for WideText

fn clone(&self) -> WideText

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl VarKind for WideText

type Element = u16

Either u8 for binary and narrow text or u16 for wide text. Wide text could also be represented as u8, after all everything is bytes. This makes it difficult though to create owned VarCell types from u16 buffers.

const ZERO: u16 = 0u16

Zero for buffer element.

const TERMINATING_ZEROES: usize = 1usize

Number of terminating zeroes required for this kind of variadic buffer.

const C_DATA_TYPE: CDataType = CDataType::WChar

fn relational_type(length: usize) -> DataType

Relational type used to bind the parameter. buffer_length is specified in elements rather than bytes, if the two differ.
