Functions

func Run 

func Run(ctx context.Context, args ...any) error

Run orchestrates one or more components. It accepts Component values (or bare func(ctx context.Context) error). It creates a context cancelled on SIGTERM or SIGINT, launches every component as a goroutine in an errgroup, and waits for all of them to finish. If any component returns an error the shared context is cancelled, signalling the remaining components to shut down. The first non-nil error (if any) is returned.

Types

type Component 

type Component func(ctx context.Context) error

Component is a long-running function that participates in the application lifecycle. It must respect ctx.Done() to allow graceful shutdown.
