data ExceptionContext Source #

Exception context represents a list of ExceptionAnnotations. These are attached to SomeExceptions via addExceptionContext and can be used to capture various ad-hoc metadata about the exception including backtraces and application-specific context.

ExceptionContexts can be merged via concatenation using the Semigroup instance or mergeExceptionContext.

Note that GHC will automatically solve implicit constraints of type ExceptionContext with emptyExceptionContext.
