Creating a new optimal filter

estimatedNumberOfItems, maxFailureRate := 3000, 0.01
bf := bloomfilter.NewFromEstimate(estimatedNumberOfItems, maxFailureRate)

Creating a new filter

sizeOfFilter, numHashFns := 128, 3
bf := bloomfilter.New(sizeOfFilter, numHashFns)

Handling values

Adding a value to the filter

valueToAdd := 'https://maliciousurl.xyz'

Checking if a value has been set

valueToCheck := 'https://maliciousurl.xyz'
bf.Check(valueToCheck) // -> true

bf.Check('value that has not been set') // -> false
