boost::urls::param_pct_view::param_pct_view

Constructor

Synopsis

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.

param_pct_view qp( "key", optional("value") ); this->key.data() == key.data() && this->value->data() == value->data() && this->has_value == true

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

Exceptions thrown on invalid input.
