Module polars_arrow::bitmap

contains Bitmap and MutableBitmap, containers of bool.

Re-exports

• pub use iterator::IntoIter;

Modules

• aligned
• bitmask
• iterator
• utils
  General utilities for bitmaps representing items where LSB is the first item.

Structs

• Bitmap
  An immutable container semantically equivalent to Arc<Vec<bool>> but represented as Arc<Vec<u8>> where each boolean is represented as a single bit.
• MutableBitmap
  A container of booleans. MutableBitmap is semantically equivalent to Vec<bool>.

Functions

• and
  Compute bitwise A AND B operation.
• and_not
  Compute bitwise A AND NOT B operation.
• binary
  Apply a bitwise operation op to two inputs and return the result as a Bitmap.
• binary_assign
  Apply a bitwise binary operation to a MutableBitmap.
• binary_assign_mut
  Apply a bitwise binary operation to a MutableBitmap.
• binary_fold
  Apply a bitwise operation op to two inputs and fold the result.
• binary_fold_mut
  Apply a bitwise operation op to two inputs and fold the result.
• chunk_iter_to_vec
  Creates a Vec<u8> from a TrustedLen of BitChunk.
• intersects_with

• quaternary
  Apply a bitwise operation op to four inputs and return the result as a Bitmap.
• select
  Compute out[i] = if selector[i] { truthy[i] } else { falsy[i] }.
• select_constant
  Compute out[i] = if selector[i] { truthy[i] } else { falsy }.
• ternary
  Apply a bitwise operation op to three inputs and return the result as a Bitmap.
• unary
  Apply a bitwise operation op to one input and return the result as a Bitmap.
• unary_assign
  Applies a function to every bit of this MutableBitmap in chunks
• xor
  Compute bitwise XOR operation.
