rendezvous - Synchronization utilities for Go

Status

Production ready.

Features

• Never leak goroutines: all functions will wait until the termination of all launched goroutines, whatever happen.

• Panics in goroutines are caught and propagated as errors.

• Task cancellation and timeout via context.Context.

• All errors are returned, either as []error or as an error that you can Unwrap() []error (see errors.Join).

API

• type Task = func() error

• WaitAll(...Task) []error

• type TaskCtx = func(context.Context) error

• WaitFirstError(...TaskCtx) error
