Can't find implicit value for canGenerateHash #30

Closed cbyn closed 7 years ago

cbyn commented 7 years ago

I'm trying to use a BloomFilter inside of a class that uses a TypeTag:

class MyClass[T: TypeTag](numberOfItems: Long, falsePositiveRate: Double) {
  val bloomFilter = BloomFilter[T](numberOfItems, falsePositiveRate)
}

However at compile time I get could not find implicit value for parameter canGenerateHash: bloomfilter.CanGenerateHashFrom[T]. Is there a way around this?

Thank you, Chris

Whoops, MyClass just needs its own implicit CanGenerateHashFrom[T] parameter and it compiles.
