Inserts an element at the end of a tuple.
Returns a new tuple with the element appended at the end, and contains
the elements in tuple followed by value as the last element.
Inlined by the compiler.
Examples
iex> tuple = {:foo, :bar}
iex> Tuple.append(tuple, :baz)
{:foo, :bar, :baz}delete_at(tuple, non_neg_integer) :: tuple
Removes an element from a tuple.
Deletes the element at the given index from tuple.
Raises an ArgumentError if index is negative or greater than
or equal to the length of tuple. Index is zero-based.
Inlined by the compiler.
Examples
iex> tuple = {:foo, :bar, :baz}
iex> Tuple.delete_at(tuple, 0)
{:bar, :baz}Creates a new tuple.
Creates a tuple of size containing the
given data at every position.
Inlined by the compiler.
Examples
iex> Tuple.duplicate(:hello, 3)
{:hello, :hello, :hello}insert_at(tuple, non_neg_integer, term) :: tuple
Inserts an element into a tuple.
Inserts value into tuple at the given index.
Raises an ArgumentError if index is negative or greater than the
length of tuple. Index is zero-based.
Inlined by the compiler.
Examples
iex> tuple = {:bar, :baz}
iex> Tuple.insert_at(tuple, 0, :foo)
{:foo, :bar, :baz}
iex> Tuple.insert_at(tuple, 2, :bong)
{:bar, :baz, :bong}
