Constants

  • MIN
    The minimum block size of a fuzzy hash.
  • NUM_VALID
    The number of valid block sizes.

Functions

  • cmp
    Compares two base 2 logarithm form of the block size values for ordering.
  • compare_sizes
    Compare two base 2 logarithm form of the block size values to determine the relation between two block sizes.
  • from_log
    Converts base 2 logarithm form of the block size to the actual one.
  • is_log_valid
    Checks whether base 2 logarithm form of the block size is valid.
  • is_near
    Checks whether two base 2 logarithm form of the block size values form a near relation (one of the three near cases).
  • is_near_eq
    Checks whether two base 2 logarithm form of the block size values form a BlockSizeRelation::NearEq relation.
  • is_near_gt
    Checks whether two base 2 logarithm form of the block size values form a BlockSizeRelation::NearGt relation.
  • is_near_lt
    Checks whether two base 2 logarithm form of the block size values form a BlockSizeRelation::NearLt relation.
  • log_from_valid
    Computes the base 2 logarithm form of a valid block size.
  • log_from_valid_unchecked⚠unsafe
    Computes the base 2 logarithm form of a valid block size but do not check whether the block size is valid.
