- [section Parser]
- A ['parser] is a [link metafunction_class template metafunction class] that
- takes the following arguments:
- * a suffix of the input text, a [link string `string`]
- * a [link source_position source position] describing at which position of the
- entire input text the suffix begins at
- The function parses a prefix of the input string.
- When the parsing is successful, it returns an [link accept `accept`] value.
- When there is a parsing error, the parser returns a [link reject `reject`]
- value. The [link is_error `is_error`] metafunction can be used to determine
- about the result of a parser if it succeeded or failed.
- The documentation refers often to the ['result of a parser]. This means that the
- parser accepts the input and refers to what [link get_result `get_result`]
- returns for the value returned by the parser.
