Struct Binary

Source 
pub struct Binary;
Expand description

Intended to be used as a generic argument for VarCell to declare that this buffer is used to hold raw binary input.

Trait Implementations§

impl Clone for Binary

Source§

fn clone(&self) -> Binary

Returns a copy of the value. Read more
1.0.0 · Source§

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

Performs copy-assignment from source. Read more
Source§

impl VarKind for Binary

Source§

const ZERO: u8 = 0u8

Zero for buffer element.
Source§

const TERMINATING_ZEROES: usize = 0usize

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

const C_DATA_TYPE: CDataType = CDataType::Binary

Source§

type Element = u8

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.
Source§

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.
