std::ranges::view_interface<D>::cbegin - cppreference.com

From cppreference.com

constexpr auto cbegin();

(1) (since C++23)

constexpr auto cbegin() const requires ranges::range<const D>;

(2) (since C++23)

The default implementation of cbegin() member function returns a constant beginning iterator of the range.

1) Let derived be a reference bound to static_cast<D&>(*this).

Equivalent to return ranges::cbegin(derived);.

2) Same as (1), except that derived is static_cast<const D&>(*this).

Return value

A constant beginning iterator of the range.

Notes

All range adaptors and range factories in the standard library and std::ranges::subrange use the default implementation of cbegin.
