func Base ¶

func Base(ctx context.Context, lg *zap.Logger) context.Context

Base initializes root logger for using as a base context. Should be done early.

The span and trace IDs must not be added to the base logger because zap can't update or replace fields.

func From ¶

func From(ctx context.Context) *zap.Logger

From returns zap.Logger from context.

func Start ¶ added in v0.3.0

func Start(ctx context.Context) (context.Context, *zap.Logger)

Start allocates new span logger and returns new context with it. Use Start to reduce allocations during From, caching the span-scoped logger.

Should be same as ctx = With(ctx), but more effective.

func With ¶

func With(ctx context.Context, fields ...zap.Field) context.Context

With returns new context with provided zap fields.

The span and trace IDs must not be added to the base logger because zap can't update or replace fields.
