param_pct_view

Construction

Synopsis

Description

This converts a param which may contain unvalidated percent-escapes into a param whose key and value are guaranteed to contain strings with no invalid percent-escapes, otherwise an exception is thrown.

The new key and value reference the same corresponding underlying character buffers. Ownership of the buffers is not transferred; the caller is responsible for ensuring that the assigned buffers remain valid until they are no longer referenced.

Example

param_pct_view qp( param_view( "key", "value" ) );

Complexity

Linear in `key.size() + value.size()`.

Exception Safety

Exceptions thrown on invalid input.
