Module arrow_buffer::buffer

Types of shared memory region

Structs

• BooleanBuffer
  A slice-able Buffer containing bit-packed booleans
• Buffer
  Buffer represents a contiguous memory region that can be shared with other buffers and across thread boundaries.
• MutableBuffer
  A MutableBuffer is Arrow’s interface to build a Buffer out of items or slices of items.
• NullBuffer
  A BooleanBuffer used to encode validity for arrow arrays
• OffsetBuffer
  A non-empty buffer of monotonically increasing, positive integers.
• RunEndBuffer
  A slice-able buffer of monotonically increasing, positive integers used to store run-ends
• ScalarBuffer
  A strongly-typed Buffer supporting zero-copy cloning and slicing

Functions

• bitwise_bin_op_helper
  Apply a bitwise operation op to two inputs and return the result as a Buffer. The inputs are treated as bitmaps, meaning that offsets and length are specified in number of bits.
• bitwise_quaternary_op_helper
  Apply a bitwise operation op to four inputs and return the result as a Buffer. The inputs are treated as bitmaps, meaning that offsets and length are specified in number of bits.
• bitwise_unary_op_helper
  Apply a bitwise operation op to one input and return the result as a Buffer. The input is treated as a bitmap, meaning that offset and length are specified in number of bits.
• buffer_bin_and
  Apply a bitwise and to two inputs and return the result as a Buffer. The inputs are treated as bitmaps, meaning that offsets and length are specified in number of bits.
• buffer_bin_or
  Apply a bitwise or to two inputs and return the result as a Buffer. The inputs are treated as bitmaps, meaning that offsets and length are specified in number of bits.
• buffer_bin_xor
  Apply a bitwise xor to two inputs and return the result as a Buffer. The inputs are treated as bitmaps, meaning that offsets and length are specified in number of bits.
• buffer_unary_not
  Apply a bitwise not to one input and return the result as a Buffer. The input is treated as a bitmap, meaning that offset and length are specified in number of bits.
