std::ranges::view_interface::cbegin - cppreference.com (original) (raw)

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).

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

[edit] Return value

A constant beginning iterator of the range.

[edit] Notes

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