Parse an authority

Synopsis

Declared in <boost/url/authority_view.hpp>

system::result<authority_view>
parse_authority(core::string_view s) noexcept;

Description

This function parses a string according to the authority grammar below, and returns an authority_view referencing the string. Ownership of the string is not transferred; the caller is responsible for ensuring that the lifetime of the string extends until the view is no longer being accessed.

BNF

authority     = [ userinfo "@" ] host [ ":" port ]

userinfo      = user [ ":" [ password ] ]

user          = *( unreserved / pct-encoded / sub-delims )
password      = *( unreserved / pct-encoded / sub-delims / ":" )

host          = IP-literal / IPv4address / reg-name

port          = *DIGIT
