bitwise operations

Bit Masking

Bit masking uses a binary pattern (mask) to select, extract, or modify specific bits within a number. By combining masks with AND, OR, and XOR operations, you can read individual flags, set groups of bits, or isolate specific fields from packed data structures.

Use Cases

  • •Feature flags and permission systems (read/write/execute)
  • •Extracting fields from packed binary protocols
  • •Subset enumeration in combinatorial algorithms
  • •Efficient set operations using bitmask representation
