ctx

Documentation

Overview

Package ctx defines the context types, which carry information defined for a specific scope (application, request, ...) A context can be passed across API boundaries and between processes.

Incoming requests to a server should create a Context, and outgoing calls to servers should accept a Context. The chain of function calls between must propagate the Context, optionally replacing it with a modified copy.

Programs that use Contexts should follow these rules to keep interfaces consistent across packages and enable static analysis tools to check context propagation
