Match a character literal.
Defined in header <boost/url/grammar/delim_rule.hpp>
constexpr implementation-defined delim_rule( char ch);
This matches the specified character. The value is a reference to the character
in the underlying buffer, expressed as a core::string_view
.
The function squelch
may be used to turn this
into void
instead. If there
is no more input, the error code error::need_more
is returned.
using value_type = core::string_view;
Rules are used with the function parse
.
system::result< core::string_view > rv = parse( "." , delim_rule( '.' ) );
char = %00-FF
