	Returns a sentinel.
sentinel	end () const =delete
	Const version of end is deleted, since the underlying view_state must be mutable.

Detailed Description

template<std::ranges::view urng_t>
class seqan3::detail::single_pass_input_view< urng_t >

Adds single_pass_input behavior to the underlying range.

Template Parameters

urng_t

The underlying range type. [view_def]

Member Typedef Documentation

urng_iterator_type

template<std::ranges::view urng_t>

using seqan3::detail::single_pass_input_view< urng_t >::urng_iterator_type = std::ranges::iterator_t<urng_t>

private

[view_def]

The iterator type for the underlying range.

Member Function Documentation

begin()

template<std::ranges::view urng_t>

iterator seqan3::detail::single_pass_input_view< urng_t >::begin ( )

inline

Returns an iterator to the current begin of the underlying range.

Subsequent calls to begin will result in different positions if the iterator was incremented between the calls.
