Middleware
Each middleware implements a function with the following signature
func (middleware CatchMiddleware) Run(
invocation *models.PipelineInvocation,
result *models.RunResult,
next func(*models.PipelineInvocation, *models.RunResult),
logger *logging.MiddlewareLogger,
stack *middleware.Stack) {}
Built-in middleware
catch - Error Handler
dir - Directory Navigator
docker - Docker Executor
each - Input Duplicator
timer - Directory Timer Middleware

Overview ¶
Package middleware slices the implementation into middlewares, each performing side effects and adapting the run based on provided arguments
