Implementations§

Source§

impl NullMask

Source

pub fn serialize(input: &SqlTuple) -> Bytes

Writes out a bit vector that sets a bit for every null value.

§Examples

let test = SqlTuple(vec![Some(BaseSqlTypes::Bool(true)),
    Some(BaseSqlTypes::Bool(true)),
    Some(BaseSqlTypes::Bool(true)),
    ]);

let mask = NullMask::serialize(&test);
assert_eq!(hex!("00").to_vec(), mask);
Source

pub fn parse( buffer: &mut impl Buf, column_count: usize, ) -> Result<Vec<bool>, NullMaskError>
