Package baggage provides base types and functionality to store and retrieve
|
|
baggage in Go context. This package exists because the OpenTracing bridge to
|
|
OpenTelemetry needs to synchronize state whenever baggage for a context is
|
|
modified and that context contains an OpenTracing span. If it were not for
|
|
this need this package would not need to exist and the
|
|
`go.opentelemetry.io/otel/baggage` package would be the singular place where
|
|
W3C baggage is handled.
