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 Extract ¶
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.
Example (Unary) ¶
Simple unary handler that adds custom fields to the requests's context. These will be used for all log statements.
ctx := context.Background()
// setting tags will be added to the logger as log fields
grpc_ctxtags.Extract(ctx).Set("custom_tags.string", "something").Set("custom_tags.int", 1337)
// Extract a single request-scoped logrus.Logger and log messages.
l := ctxlogrus.Extract(ctx)
l.Info("some ping")
l.Info("another ping")
