class Tkrzw::Utility

Deserializes a big-endian binary sequence into a floating-point number.

• @param data a binary sequence.

• @return The result floating-point number.

# File tkrzw.rb, line 104
def self.deserialize_float(data)
  # (native code)
end

Deserializes a big-endian binary sequence into an integer.

• @param data a binary sequence.

• @return The result integer.

# File tkrzw.rb, line 90
def self.deserialize_int(data)
  # (native code)
end

Gets the Levenshtein edit distance of two strings.

• @param a A string.

• @param b The other string.

• @param utf If true, strings are treated as UTF-8 and the edit distance is by the Unicode character.

• @return The Levenshtein edit distance of the two strings.

end

Gets the memory capacity of the platform.

• @return The memory capacity of the platform in bytes, or -1 on failure.

# File tkrzw.rb, line 45
def self.get_memory_capacity()
  # (native code)
end

Gets the current memory usage of the process.

• @return The current memory usage of the process in bytes, or -1 on failure.

Primary hash function for the hash database.

• @param data The data to calculate the hash value for.

• @param num_buckets The number of buckets of the hash table. If it is omitted, UINT64MAX is set.

• @return The hash value.

end

Secondary hash function for sharding.

• @param data The data to calculate the hash value for.

• @param num_shards The number of shards. If it is omitted, UINT64MAX is set.

• @return The hash value.
