Constructor

Synopsis

Declared in <boost/url/param.hpp>

template<class OptionalString>
param_view(
    core::string_view key,
    OptionalString const& value) noexcept;

Description

This constructs a parameter with a key and value. No validation is performed on the strings. 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_view qp( "key", "value" );

Postconditions

this->key.data() == key.data() && this->value.data() == value.data() && this->has_value == true

Complexity

Constant.

Exception Safety

Throws nothing.
