Span should mimic std::span.

Methods¶

Span subspan(
    std::size_t offset,
    std::size_t size = std::numeric_limits<std::size_t>::max()
    ) const

return sub part of span starting from offset and not greater than size

Span& drop_front(std::size_t number_of_elements)

drop number of elements from front

Span& drop_back(std::size_t number_of_elements)

drop number of elements from back
