explicit ClientImpl(
    const capro::ServiceDescription & service,
    const ClientOptions & clientOptions ={}
)

Constructor for a client.

Parameters:

• clientOptions like the queue capacity and queue full policy by a client

function ~ClientImpl

virtual ~ClientImpl()

function ClientImpl

ClientImpl(
    const ClientImpl & 
)

function ClientImpl

ClientImpl(
    ClientImpl && 
)

function operator=

ClientImpl & operator=(
    const ClientImpl & 
)

function operator=

ClientImpl & operator=(
    ClientImpl && 
)

function loan

template <typename... Args>
cxx::expected< Request< Req >, AllocationError > loan(
    Args &&... args
)

Get a Request from loaned shared memory and construct the data with the given arguments.

Parameters:

• args Arguments used to construct the data.

Return: An instance of the Request that resides in shared memory or an error if unable to allocate memory to loan.

The loaned Request is automatically released when it goes out of scope.

function send

cxx::expected< ClientSendError > send(
    Request< Req > && request
) override

Sends the given Request and then releases its loan.

Parameters:

• request to send.

Return: Error if sending was not successful

function take

cxx::expected< Response< const Res >, ChunkReceiveResult > take()
