Functions ¶

func ConfigFromContext ¶

func ConfigFromContext(ctx context.Context) (*configx.Provider, error)

ConfigFromContext returns the configuration provider from the context or an error if no configuration provider is found in the context.

Example ¶

ctx := context.Background()

config, err := configx.New(ctx, []byte(`{"type":"object","properties":{"foo":{"type":"string"}}}`), configx.WithValue("foo", "bar"))
if err != nil {
	panic(err)
}

ctx = WithConfig(ctx, config)
fmt.Printf("foo = %s", MustConfigFromContext(ctx).String("foo"))

Output:

foo = bar

func IsRootContext ¶

func IsRootContext(ctx context.Context) bool

func MustConfigFromContext ¶

func MustConfigFromContext(ctx context.Context) *configx.Provider

MustConfigFromContext returns the configuration provider from the context or panics if no configuration provider is found in the context.

func SetNIDContext ¶

func SetNIDContext(ctx context.Context, nid uuid.UUID) context.Context

SetNIDContext sets the nid for the given context.

func WithConfig ¶

func WithConfig(ctx context.Context, p *configx.Provider) context.Context

WithConfig returns a new context with the given configuration provider.
