Detailed Description

This namespace implements a wrapper for the Cassandra C++ driver.

Function Documentation

template<typename... Types>

impl::ResultExtractor< Types... > data::cassandra::extract ( Handle::ResultType const & result )

nodiscard

Extracts the results into series of std::tuple<Types...> by creating a simple wrapper with an STL input iterator inside.

You can call .begin() and .end() in order to iterate as usual. This also means that you can use it in a range-based for or with some algorithms.

Template Parameters

Types The types to extract

Parameters

result The result to iterate

template<SomeSettingsProvider SettingsProviderType>

std::string data::cassandra::qualifiedTableName	(	SettingsProviderType const &	provider,
		std::string_view	name )

inlinenodiscard

Returns the table name qualified with the keyspace and table prefix.

Template Parameters

SettingsProviderType The settings provider type

Parameters

provider	The settings provider
name	The name of the table
