Member Function Documentation

◆ back()

template<typename T, typename TTraits = etl::char_traits<T>>
ETL_CONSTEXPR const_reference etl::basic_string_view< T, TTraits >::back ( ) const
inline

Returns a const reference to the last element. If asserts or exceptions are enabled, throws an etl::string_view_empty if the view is empty.

◆ front()

template<typename T, typename TTraits = etl::char_traits<T>>
ETL_CONSTEXPR const_reference etl::basic_string_view< T, TTraits >::front ( ) const
inline

Returns a const reference to the first element. If asserts or exceptions are enabled, throws an etl::string_view_empty if the view is empty.

◆ operator[]()

template<typename T, typename TTraits = etl::char_traits<T>>
ETL_CONSTEXPR const_reference etl::basic_string_view< T, TTraits >::operator[] ( size_t i) const
inline

Returns a const reference to the indexed value. If asserts or exceptions are enabled, throws an etl::string_view_bounds if the index is out of bounds.
