Module aerospike::operations::bitwise

Bit operations. Create bit operations used by client operate command. Offset orientation is left-to-right. Negative offsets are supported. If the offset is negative, the offset starts backwards from end of the bitmap. If an offset is out of bounds, a parameter error will be returned.

Nested CDT operations are supported by optional CTX context arguments. Example:

use aerospike::operations::bitwise::{resize, BitwiseResizeFlags, BitPolicy};
// bin = [[0b00000001, 0b01000010], [0b01011010]]
// Resize first bitmap (in a list of bitmaps) to 3 bytes.
resize("bin", 3, Some(BitwiseResizeFlags::Default), &BitPolicy::default());
// bin result = [[0b00000001, 0b01000010, 0b00000000], [0b01011010]]

Structs

• BitPolicy
  BitPolicy determines the Bit operation policy.

Enums

• BitwiseOverflowActions
  CdtBitwiseOverflowActions specifies the action to take when bitwise add/subtract results in overflow/underflow.
• BitwiseResizeFlags
  CdtBitwiseResizeFlags specifies the bitwise operation flags for resize.
• BitwiseWriteFlags
  CdtBitwiseWriteFlags specify bitwise operation policy write flags.

Functions

• add
  Creates bit “add” operation. Server adds value to byte[] bin starting at bitOffset for bitSize. BitSize must be <= 64. Signed indicates if bits should be treated as a signed number. If add overflows/underflows, CdtBitwiseOverflowAction is used. Server does not return a value.
• and
  Creates bit “and” operation. Server performs bitwise “and” on value and byte[] bin at bitOffset for bitSize. Server does not return a value.
• count
  Creates bit “count” operation. Server returns integer count of set bits from byte[] bin starting at bitOffset for bitSize.
• get
  Creates bit “get” operation. Server returns bits from byte[] bin starting at bitOffset for bitSize.
• get_int
  Creates bit “get integer” operation. Server returns integer from byte[] bin starting at bitOffset for bitSize. Signed indicates if bits should be treated as a signed number.
• insert
  Creates byte “insert” operation. Server inserts value bytes into byte[] bin at byteOffset. Server does not return a value.
• lscan
  Creates bit “left scan” operation. Server returns integer bit offset of the first specified value bit in byte[] bin starting at bitOffset for bitSize.
• lshift
  Creates bit “left shift” operation. Server shifts left byte[] bin starting at bitOffset for bitSize. Server does not return a value.
• not
  Creates bit “not” operation. Server negates byte[] bin starting at bitOffset for bitSize. Server does not return a value.
• or
  Creates bit “or” operation. Server performs bitwise “or” on value and byte[] bin at bitOffset for bitSize. Server does not return a value.
• remove
  Creates byte “remove” operation. Server removes bytes from byte[] bin at byteOffset for byteSize. Server does not return a value.
• resize
  Creates byte “resize” operation. Server resizes byte[] to byteSize according to resizeFlags. Server does not return a value.
• rscan
  Creates bit “right scan” operation. Server returns integer bit offset of the last specified value bit in byte[] bin starting at bitOffset for bitSize.
• rshift
  Creates bit “right shift” operation. Server shifts right byte[] bin starting at bitOffset for bitSize. Server does not return a value.
• set
  Creates bit “set” operation. Server sets value on byte[] bin at bitOffset for bitSize. Server does not return a value.
• set_int
  Creates bit “setInt” operation. Server sets value to byte[] bin starting at bitOffset for bitSize. Size must be <= 64. Server does not return a value.
• subtract
  Creates bit “subtract” operation. Server subtracts value from byte[] bin starting at bitOffset for bitSize. bit_size must be <= 64. Signed indicates if bits should be treated as a signed number. If add overflows/underflows, CdtBitwiseOverflowAction is used. Server does not return a value.
• xor
  Creates bit “exclusive or” operation. Server performs bitwise “xor” on value and byte[] bin at bitOffset for bitSize. Server does not return a value.
