Struct BitMaskView 

pub struct BitMaskView<'a> { /* private fields */ }

Optional validity / analysis mask as a packed bitmap (1 = valid/included).

Implementations

impl<'a> BitMaskView<'a>

pub fn new(bytes: &'a [u8], len: usize) -> Result<Self, ViewError>

Create a mask covering len bits.

Errors

When bytes is shorter than ceil(len / 8).

pub const fn len(self) -> usize

Number of bits.

pub const fn is_empty(self) -> bool

Whether empty.

pub fn get(self, i: usize) -> bool

Whether bit i is set.
