Link to this function append(tuple, value) View Source
append(tuple, term) :: tuple

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}
Link to this function delete_at(tuple, index) View Source
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}
Link to this function duplicate(data, size) View Source
duplicate(term, non_neg_integer) :: tuple

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}
Link to this function insert_at(tuple, index, value) View Source
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}
Link to this function to_list(tuple) View Source
to_list(tuple) :: list

Converts a tuple to a list.

Returns a new list with all the tuple elements.

Inlined by the compiler.

Examples

iex> tuple = {:foo, :bar, :baz}
iex> Tuple.to_list(tuple)
[:foo, :bar, :baz]
