Detailed Description

URL Component representations using offsets.

We design the url_components struct so that it is as small and simple as possible. This version uses 32 bytes.

This struct is used to extract components from a single 'href'.

Member Function Documentation

◆ check_offset_consistency()

bool ada::url_components::check_offset_consistency ( ) const
noexcept

Check the following conditions: protocol_end < username_end < ... < hash_start, expect when a value is omitted. It also computes a lower bound on the possible string length that may match these offsets.

Returns
true if the offset values are consistent with a possible URL string
