----

== Description


If `s` is a valid percent-encoded string,
the function returns the buffer as a valid
view which may be used to perform decoding
or measurements.
Otherwise the result contains an error code.
Upon success, the returned view references
the original character buffer;
Ownership is not transferred.

=== Complexity

Linear in `s.size()`.

=== Exception Safety

Throws nothing.
