Detailed Description

template<std::ranges::viewable_range range_t>
struct seqan3::detail::make_aligned_sequence_type< range_t >

A transformation trait that returns the correct aligned sequence type for a given sequence type.

Template Parameters

range_t

The range type to be transformed.

This transformation trait helps to define the correct type representing the aligned sequence. The aligned sequence type is defined as follows:

• a seqan3::gap_decorator over a slice of an instance of range_t, if it is constructible, otherwise
• a std::vector over the seqan3::gapped alphabet over the value type of range_t.

Note some ranges cannot be decorated with the seqan3::gap_decorator, e.g. a non-random access range. In this case the fallback is to always use std::vector and copy the content from the passed range to the vector.
