Struct BitmapBuilder

pub struct BitmapBuilder { /* private fields */ }

Used to build bitmaps bool-by-bool in sequential order.

Implementations

impl BitmapBuilder

pub fn new() -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn capacity(&self) -> usize

pub fn set_bits(&self) -> usize

pub fn unset_bits(&self) -> usize

pub fn with_capacity(bits: usize) -> Self

pub fn reserve(&mut self, additional: usize)

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

pub unsafe fn push_unchecked(&mut self, x: bool)

Safety

self.len() < self.capacity() must hold.

pub fn extend_constant(&mut self, length: usize, value: bool)

pub unsafe fn push_word_with_len_unchecked(&mut self, word: u64, length: usize)

Pushes the first length bits from the given word, assuming the rest of the bits are zero.

Safety

self.len + length <= self.cap and length <= 64 must hold.

pub fn extend_from_slice(&mut self, slice: &[u8], offset: usize, length: usize)

pub fn extend_from_bitmap(&mut self, bitmap: &Bitmap)

pub fn into_mut(self) -> MutableBitmap

Converts this BitmapBuilder into a mutable bitmap.

pub fn into_opt_mut_validity(self) -> Option<MutableBitmap>

The same as into_mut, but returns None if the bitmap is all-ones.

pub fn freeze(self) -> Bitmap

Freezes this BitmapBuilder into an immutable Bitmap.

pub fn into_opt_validity(self) -> Option<Bitmap>

The same as freeze, but returns None if the bitmap is all-ones.

pub fn extend_trusted_len_iter<I>(&mut self, iterator: I)

where I: Iterator<Item = bool> + TrustedLen,

pub fn from_trusted_len_iter<I>(iterator: I) -> Self

where I: Iterator<Item = bool> + TrustedLen,

fn clone(&self) -> BitmapBuilder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for BitmapBuilder

fn default() -> BitmapBuilder

Returns the “default value” for a type.
