Instance Method Summary

• #[] (key : K) : V
• #[]= (key : K, value : V) : V
• #[]? (key : K) : V | Nil
• #at (index : Int) : Tuple(K, V)
• #at (index : Int, &)

  Returns the key-value at the index -th.

• #at? (index : Int) : Tuple(K, V) | Nil

  Like #at , but returns nil if trying to access an key-value outside the set's range.

• #delete (key : K) : V | Nil
• #each (&) : Nil

  Must yield this collection's elements to the block.

• #each : Iterator(Tuple(K, V))

  Must return an Iterator over the elements in this collection.

• #fetch (key : K, &)
• #fetch (key : K, default_value)
• #fetch_at (index : Int, &)
• #fetch_at (index : Int, default_value)
• #has_key? (key : K) : Bool
• #invert : SqrtMap(V, K)
• #key_at (index : Int) : K

  Returns the key at the index -th.

• #key_at? (index : Int) : K | Nil

  Like #at , but returns nil if trying to access an key outside the set's range.

• #key_for (value) : K
• #key_for (value, &)
• #key_for? (value) : K | Nil
• #keys : Array(K)
• #put (key : K, value : V, &)
• #size (*args, **options)
• #size (*args, **options, &)
• #unsafe_fetch (index : Int) : Tuple(K, V)
• #update (key : K, & : V -> V) : V
• #value_at (index : Int) : V

  Returns the value at the index -th.

• #value_at? (index : Int) : V | Nil

  Like #at , but returns nil if trying to access an value outside the set's range.

• #values : Array(V)
• #values_at (*indices : Int)
• #values_by_key (*keys : K)
