connection_pool::connection_pool (3 of 4 overloads)

Constructs a connection pool.

Synopsis
template<
    class ExecutionContext>
connection_pool(
    ExecutionContext& ctx,
    pool_params params);
Description

Both internal I/O objects and connections are constructed using ctx.get_executor().

The pool is created in a "not-running" state. Call async_run to transition to the "running" state. Calling async_get_connection in the "not-running" state will fail with client_errc::cancelled.

The constructed pool is always valid (this->valid() == true).

This function participates in overload resolution only if ExecutionContext satisfies the ExecutionContext requirements imposed by Boost.Asio.
