Detailed Description

template<class Self_tp>
class mysql::strconv::detail::Parse_position< Self_tp >

Base class for the current position of a string parser, holding both the parsed string and the position within the parsed string.

Subclasses are contiguous iterators over the characters in the parsed string.

Template Parameters

Self_tp

The subclass inheriting from this class.

Member Typedef Documentation

Iterator_category_t

template<class Self_tp >

using mysql::strconv::detail::Parse_position< Self_tp >::Iterator_category_t = std::contiguous_iterator_tag

Constructor & Destructor Documentation

Parse_position() [1/2]

template<class Self_tp >

mysql::strconv::detail::Parse_position< Self_tp >::Parse_position ( const std::string_view &  source, std::size_t  int_pos = 0  )

inlineexplicit

Construct a new Parse_position from the given range.

Parameters

source	Source string.
int_pos	Current position. Defaults to 0, i.e., the beginning.

Parse_position() [2/2]

template<class Self_tp >

mysql::strconv::detail::Parse_position< Self_tp >::Parse_position ( )

default

Construct a new object.

The object cannot be used for anything besides assigning another object to it.
