Functions

func Persist

func Persist(ctx context.Context, key any, value any) context.Context

Persist will store the key-value pair in provided context. Either wrapping it in a persistent context that supports multiple value storage, or digging through the context stack for an existing persistent context into which it will store the key-value pair. This allows storing and accessing context values across multiple layers of a callstack, both forwards and backwards.

Types

type PersistCtx

type PersistCtx struct {
	// embedded base ctx.
	context.Context
	// contains filtered or unexported fields
}

persistctx wraps a base context.Context in order to provide persistent key-value storage across both directions of a callstack.

func Get

func Get(ctx context.Context) *PersistCtx

Get will wrap the provided context in a PersistCtx, or return an existing copy if found in the context stack.

func (*PersistCtx) Set

func (ctx *PersistCtx) Set(key any, value any)

Set will safely set the key-value pair in context "map".

func (*PersistCtx) Value

func (ctx *PersistCtx) Value(key any) any

Value implements context.Context's Value().
