@returns true if the listener thread is currently running and is joinable, false otherwise

reserves space for the specified number of elements. Makes sure the old data fits. exactly the same as reserve(c).

This pointer is guaranteed to always be valid once this instance has been constructed. It points to the subsmgr unique_ptr which this instance owns.

Return true if the wrapped FILE* is nullptr, false otherwise. */

* Read the specified number of bits from the stream. The data is returned * in the nbits least significant bits of a 64-bit uint. */

Return a 16-byte hash for 48 bytes. Quick and dirty. Callers do best to use "random-looking" values for a and b.

Returns a locking context. Use context.append() to write batches of records to the end of the DB. The locked context is released on BatchWriteContext

result might be undefined when input_num is zero */

Convert a field element to a 32-byte big endian value. Requires the input to be normalized */

This is thread-safe. Returns the number of SIGINT, etc signals that were caught. If this is ever above 0, the app is about to exit. This is provided i

Helper to get a column family name. `cf` may be nullptr

Attempts to compute i * 10^(power) exactly; and if "negative" is true, negate the result. This function will only work in some cases, when it does not

returns a value with the high 16 bits set if not valid otherwise returns the conversion of the 4 hex digits at src into the bottom 16 bits of the 32-b

Leaving these here so they can be inlined if so desired

Convert a mantissa, an exponent and a sign bit into an ieee64 double. The real_exponent needs to be in [0, 2046] (technically real_exponent = 2047 wou
