NewSingletonInjector always injects the given value using the given context key.

type Releaser

type Releaser func()

Releaser releases an initialized resource.

func NewCloseReleaser

func NewCloseReleaser(closer io.Closer) Releaser

NewCloseReleaser returns a releaser that calls closer.Close, ignoring any returned error.

func NewNoopReleaser
