param_pct_view::param_pct_view (2 of 4 overloads)

Constructor.

Synopsis
param_pct_view(
    pct_string_view key,
    pct_string_view value);
Description

This constructs a parameter with a key and 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
[link url.ref.boost__urls__param_pct_view.param_pct_view `param_pct_view`] qp( "key" , "value" );
Postconditions
this->[link url.ref.boost__urls__param_pct_view.key `key`].[link url.ref.boost__urls__pct_string_view.data `data`]() == [link url.ref.boost__urls__param_pct_view.key `key`].[link url.ref.boost__urls__pct_string_view.data `data`]() && this->[link url.ref.boost__urls__param_pct_view.value `value`].[link url.ref.boost__urls__pct_string_view.data `data`]() == [link url.ref.boost__urls__param_pct_view.value `value`].[link url.ref.boost__urls__pct_string_view.data `data`]() && this->[link url.ref.boost__urls__param_pct_view.has_value `has_value`] == true
Complexity

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