data BacktraceMechanism Source #
How to collect a backtrace when an exception is thrown.
CostCentreBacktrace | collect cost-centre stack backtraces (only available when built with profiling) |
HasCallStackBacktrace | collect |
ExecutionBacktrace | collect backtraces via native execution stack unwinding (e.g. using DWARF debug information) |
IPEBacktrace | collect backtraces from Info Table Provenance Entries |
getBacktraceMechanismState :: BacktraceMechanism -> IO Bool Source #
Will the given BacktraceMechanism
be used when collecting
backtraces?
setBacktraceMechanismState :: BacktraceMechanism -> Bool -> IO () Source #
Set whether the given BacktraceMechanism
will be used when collecting
backtraces?
Collecting backtraces
displayBacktraces :: Backtraces -> String Source #
Render a set of backtraces to a human-readable string.
collectBacktraces :: (?callStack :: CallStack) => IO Backtraces Source #
Collect a set of Backtraces
