Instance Method Summary

• #<=>(other : ULID)

  implementing <=> and including Comparable will give us == for free

• #hash(hasher)

  Define a hash(hasher) method based on @value Between #hash and #==, we can use ULID objects as values in Hashes

• #to_i : UInt128
• #to_s(io : IO) : Nil

  Appends a short String representation of this object which includes its class name and its object address.

• #to_u128 : UInt128
• #to_uuid
• #value : UInt128
• #value=(value : UInt128)
