Overview ¶

Package metadata provides utilities for attaching and retrieving metadata from Go contexts. It offers both simple key-value storage and a specialized context implementation that supports string-keyed metadata for efficient data passing between function calls.

Index ¶

func MetaFrom(ctx context.Context) map[string]any
func WithMeta(ctx context.Context, m map[string]any) context.Context
func WithValues(ctx context.Context, data map[string]any) context.Context

Functions ¶

func MetaFrom ¶

func MetaFrom(ctx context.Context) map[string]any

MetaFrom extracts metadata from the given context. Returns nil if no metadata is found or if the stored value is not a valid metadata map.

func WithMeta ¶

func WithMeta(ctx context.Context, m map[string]any) context.Context

WithMeta returns a new context with the provided metadata map attached. The metadata can be retrieved later using MetaFrom.

func WithValues ¶

func WithValues(ctx context.Context, data map[string]any) context.Context

WithValues creates a new context with additional string-keyed metadata. The metadata is accessible through the Value method using string keys. Returns the original context if no data is provided.
