+// TConfiguration defines some configurations shared between TTransport,

+//
+// When constructing TConfiguration, you only need to specify the non-default
+// fields. All zero values have sane default values.
+//
+// Not all configurations defined are applicable to all implementations.
+// Implementations are free to ignore the configurations not applicable to them.
+//
+// All functions attached to this type are nil-safe.
+//
+// See [1] for spec.
+//
+// NOTE: When using TConfiguration, fill in all the configurations you want to
+// set across the stack, not only the ones you want to set in the immediate
+// TTransport/TProtocol.
+//
+// For example, say you want to migrate this old code into using TConfiguration:
+//
+// sccket := thrift.NewTSocketTimeout("host:port", time.Second)

+// thrift.NewTTransportFactory(),
+// 1024 * 1024 * 256,
+// )
+// protoFactory := thrift.NewTBinaryProtocolFactory(true, true)
+//
+// This is the wrong way to do it because in the end the TConfiguration used by
+// socket and transFactory will be overwritten by the one used by protoFactory
+// because of TConfiguration propagation:
+//
+// // bad example, DO NOT USE
+// sccket := thrift.NewTSocketConf("host:port", &thrift.TConfiguration{
+// ConnectTimeout: time.Second,
+// SocketTimeout: time.Second,
+// })

+// TBinaryStrictRead: thrift.BoolPtr(true),
