^---------
Error: this 'initialize' doesn't explicitly initialize instance variable '@bytesize' of BloomFilter::Filter, rendering it nilable
The instance variable '@bytesize' is initialized in other 'initialize' methods,
and by not initializing it here it's not clear if the variable is supposed
to be nilable or if this is a mistake.
To fix this error, either assign nil to it here:
@bytesize = nil
Or declare it as nilable outside at the type level:
@bytesize : (UInt32)?
