Constructor
Synopsis
Declared in header <boost/url/param.hpp>
template<class OptionalString>
param_pct_view(
pct_string_view key,
OptionalString const& value);
Description
This constructs a parameter with a key and optional value, which may both contain percent escapes.
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( "key", optional<core::string_view>("value") );
Postconditions
this->key.data() == key.data() && this->value->data() == value->data() && this->has_value == true
Complexity
Linear in key.size() + value->size()
.
Exception Safety
