Types ¶
type Group ¶
type Group struct {
Results []Result
// contains filtered or unexported fields
}
A Group is reference to errgroup package
func NewGroup ¶
func NewGroup() *Group
NewGroup returns a new Group and an associated Context derived from ctx.
The derived Context is canceled the first time a function passed to Go returns a non-nil error or the first time Wait returns, whichever occurs first.
func (*Group) Go ¶
Go calls the given function in a new goroutine. It blocks until the new goroutine can be added without the number of active goroutines in the group exceeding the configured limit.
The first call to return a non-nil error cancels the group's context, if the group was created by calling WithContext. The error will be returned by Wait.
func (*Group) SetLimit ¶
SetLimit limits the number of active goroutines in this group to at most n. A negative value indicates no limit.
Any subsequent call to the Go method will block until it can add an active goroutine without exceeding the configured limit.
The limit must not be modified while any goroutines in the group are active.
