Member Functions

Name	Return Type	Description
`front()`	`reference`	Returns a reference to the first element.
`front() const`	`const_reference`	Returns a const reference to the first element
`back()`	`reference`	Returns a reference to the last element.
`back() const`	`const_reference`	Returns a const reference to the last element.
`data()`	`pointer`	Returns a pointer to the underlying data.
`data() const`	`const_pointer`	Returns a pointer to the underlying data.
`operator[](size_type)`	`reference`	Returns a reference to the element at the specified index.
`operator[](size_type) const`	`const_reference`	Returns a reference to the element at the specified index.
`begin()`	`iterator`	Returns an iterator to the beginning.
`begin() const`	`const_iterator`	Returns an iterator to the beginning.
`end()`	`iterator`	Returns an iterator to the end.
`end() const`	`const_iterator`	Returns an iterator to the end.
`cbegin() const`	`const_iterator`	Returns an iterator to the beginning.
`cend() const`	`const_iterator`	Returns an iterator to the end.
`rbegin()`	`reverse_iterator`	Returns a reverse iterator to the beginning.
`rbegin() const`	`const_reverse_iterator`	Returns a reverse iterator to the beginning.
`rend()`	`reverse_iterator`	Returns a reverse iterator to the end.
`rend() const`	`const_reverse_iterator`	Returns a reverse iterator to the end.
`crbegin() const`	`const_reverse_iterator`	Returns a reverse iterator to the beginning.
`crend() const`	`const_reverse_iterator`	Returns a reverse iterator to the end.
`empty() const`	`bool`	Returns if the array is empty.
`size() const`	`size_type`	Returns the size of the array.
`fill(const value_type&)`	`void`	Fills the array with the specified value.

Non-member Functions

Name	Return Type	Description
`operator==(lhs, rhs)`	`bool`	Returns if two arrays are equal.
`operator!=(lhs, rhs)`	`bool`	Returns if two arrays are not equal.
`operator<(lhs, rhs)`	`bool`	Returns if the left array is lexicographically less.
`operator<=(lhs, rhs)`	`bool`	Returns if the left array is lexicographically less or equal.
`operator>(lhs, rhs)`	`bool`	Returns if the left array is lexicographically greater.
`operator>=(lhs, rhs)`	`bool`	Returns if the left array is lexicographically greater or equal.

Deduction Guide

Guide	Description
`array(T, Ts...) -> array<T, sizeof...(Ts) + 1>`	Deduces type and size from constructor arguments

Specialization

Specialization	Description
`array<T, 0>`	Behaves as an empty container; `data()` returns null and accessors are undefined behaviour.

Example

#include <opentl/array.hpp>

int main() {
    opentl::array<int, 3> arr{1, 2, 3};
    arr[0] = 10;
    for (auto x : arr) { /* ... */ }
    arr.fill(0);
}
