Struct BitVec 

pub struct BitVec { /* private fields */ }

Compact bit vector backed by a packed Vec<u8>.

Bit ordering (LOAD-BEARING - this is part of the FFI wire format): bit i lives in byte i / 8, position i % 8, LSB-first within the byte. Setting bit 0 of an empty 8-bit byte yields 0b0000_0001. The FFI ABI’s defined_bitvec and any borrowed Bool column data depend on this exact layout. Do not change.

Implementations

impl BitVec

pub fn repeat(len: usize, value: bool) -> Self

pub fn from_slice(slice: &[bool]) -> Self

pub fn empty() -> Self

pub fn from_fn(len: usize, f: impl FnMut(usize) -> bool) -> Self

pub fn take(&self, n: usize) -> BitVec

pub fn extend(&mut self, other: &BitVec)

pub fn clear(&mut self)

Clear all bits, retaining the allocated capacity when solely owned.

pub fn push(&mut self, bit: bool)

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn capacity(&self) -> usize

pub fn as_packed_bytes(&self) -> &[u8]

Borrow the packed byte representation.

Length is len.div_ceil(8) bytes. Bit ordering is LSB-first within each byte (see type-level doc). Used by the FFI marshal path to hand guests a zero-copy view of bool columns and option-defined bitmaps.

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

pub fn set(&mut self, idx: usize, value: bool)

pub fn iter(&self) -> BitVecIter

pub fn and(&self, other: &Self) -> Self

pub fn to_vec(&self) -> Vec<bool>

pub fn count_ones(&self) -> usize

pub fn all_ones(&self) -> bool

pub fn count_zeros(&self) -> usize

pub fn any(&self) -> bool

pub fn none(&self) -> bool

pub fn not(&self) -> Self

pub fn or(&self, other: &Self) -> Self

pub fn is_owned(&self) -> bool

pub fn is_shared(&self) -> bool

pub fn with_capacity(capacity: usize) -> Self

pub fn try_into_raw(self) -> Result<(Vec<u8>, usize), Self>

Try to extract the underlying bytes Vec without cloning. Returns Ok((Vec<u8>, len)) if this is the sole owner, Err(self) otherwise.

pub fn from_raw(bits: Vec<u8>, len: usize) -> Self

Reconstruct a BitVec from raw parts previously obtained via try_into_raw.

pub fn reorder(&mut self, indices: &[usize])

impl Debug for BitVec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BitVec

fn default() -> Self

Returns the “default value” for a type.

impl Deref for BitVec

type Target = BitVecInner

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for BitVec

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BitVec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&BitVec> for BitVec

fn from(value: &BitVec) -> Self

Converts to this type from the input type.

impl<const N: usize> From<[bool; N]> for BitVec

fn from(value: [bool; N]) -> Self
