Documentation

Overview

`ctxlogrus` is a ctxlogger that is backed by logrus

It accepts a user-configured `logrus.Logger` that will be used for logging. The same `logrus.Logger` will be populated into the `context.Context` passed into gRPC handler code.

You can use `ctx_logrus.Extract` to log into a request-scoped `logrus.Logger` instance in your handler code.

As `ctx_logrus.Extract` will iterate all tags on from `grpc_ctxtags` it is therefore expensive so it is advised that you extract once at the start of the function from the context and reuse it for the remainder of the function (see examples).

Please see examples and tests for examples of use.

Functions

func AddFields

func AddFields(ctx context.Context, fields logrus.Fields)

AddFields adds logrus fields to the logger.

func Extract

func Extract(ctx context.Context) *logrus.Entry

Extract takes the call-scoped logrus.Entry from ctx_logrus middleware.

If the ctx_logrus middleware wasn't used, a no-op `logrus.Entry` is returned. This makes it safe to use regardless.

func ToContext

func ToContext(ctx context.Context, entry *logrus.Entry) context.Context

ToContext adds the logrus.Entry to the context for extraction later. Returning the new context that has been created.
