@spec instrument(String.t(), function()) :: any()

Instrument a function.

def call do
  Appsignal.instrument("foo.bar", fn ->
    :timer.sleep(1000)
  end)
end

When passing a function that takes an argument, the function is called with the created span to allow adding extra information.

def call(params) do
  Appsignal.instrument("foo.bar", fn span ->
    Appsignal.Span.set_sample_data(span, "params", params)
    :timer.sleep(1000)
  end)
end

@spec instrument(String.t(), String.t(), function()) :: any()

Instrument a function, and set the "appsignal:category" attribute to the value passed as the category argument.

@spec send_error(Exception.t(), Exception.stacktrace()) :: Appsignal.Span.t() | nil

Send an error in a newly created Appsignal.Span.

@spec send_error(Exception.t(), Exception.stacktrace(), function()) ::
  Appsignal.Span.t() | nil

@spec send_error(Exception.kind(), any(), Exception.stacktrace()) ::
  Appsignal.Span.t() | nil

Send an error in a newly created Appsignal.Span. Calls the passed function with the created Appsignal.Span before closing it.

@spec set_error(Exception.t(), Exception.stacktrace()) :: Appsignal.Span.t() | nil

Set an error in the current root span.

@spec set_error(Exception.kind(), any(), Exception.stacktrace()) ::
  Appsignal.Span.t() | nil

Set an error in the current root span by passing a kind and reason.
