Types

type MiddlewareKind

type MiddlewareKind string

const (
	MiddlewareKindJobInsert MiddlewareKind = "job_insert"
	MiddlewareKindWorker    MiddlewareKind = "worker"
)

type MiddlewareLookupInterface

type MiddlewareLookupInterface interface {
	ByMiddlewareKind(kind MiddlewareKind) []rivertype.Middleware
}

MiddlewareLookupInterface is an interface to look up middlewares by middleware kind. It's commonly implemented by MiddlewareLookup, but may also be EmptyMiddlewareLookup as a memory allocation optimization for bundles where no middlewares are present.

func NewMiddlewareLookup

func NewMiddlewareLookup(middlewares []rivertype.Middleware) MiddlewareLookupInterface

NewMiddlewareLookup returns a new middleware lookup interface based on the given middlewares that satisfies MiddlewareLookupInterface. This is often middlewareLookup, but may be emptyMiddlewareLookup as an optimization for the common case of an empty middleware bundle.
