gopkg.in/rollbar/rollbar-go.v1 (go): Package rollbar is a Golang Rollbar client that makes it easy to report errors to Rollbar with full stacktraces.  Basic Usage  This package is designed to be used via the functions exposed at the root of the `rollbar` package. These work by managing a single instance of the `Client` type that is configurable via the setter functions at the root of the package.  If you wish for more fine grained control over the client or you wish to have multiple independent clients then you can create and manage your own instances of the `Client` type.  We provide two implementations of the `Transport` interface, `AsyncTransport` and `SyncTransport`. These manage the communication with the network layer. The Async version uses a buffered channel to communicate with the Rollbar API in a separate go routine. The Sync version is fully synchronous. It is possible to create your own `Transport` and configure a Client to use your preferred implementation.  Go does not provide a mechanism for handling all panics automatically, therefore we provide two functions `Wrap` and `WrapAndWait` to make working with panics easier. They both take a function and then report to Rollbar if that function panics. They use the recover mechanism to capture the panic, and therefore if you wish your process to have the normal behaviour on panic (i.e. to crash), you will need to re-panic the result of calling `Wrap`. For example,  The above pattern of calling `Wrap(...)` and then `Wait(...)` can be combined via `WrapAndWait(...)`. When `WrapAndWait(...)` returns if there was a panic it has already been sent to the Rollbar API. The error is still returned by this function if there is one.  Due to the nature of the `error` type in Go, it can be difficult to attribute errors to their original origin without doing some extra work. To account for this, we define the interface `CauseStacker`:  One can implement this interface for custom Error types to be able to build up a chain of stack traces. In order to get stack the correct stacks, callers must call BuildStack on their own at the time that the cause is wrapped. This is the least intrusive mechanism for gathering this information due to the decisions made by the Go runtime to not track this information.
