Detailed Description

HookContext allows passing arbitrary data from the caller through to hooks.

Example use case:

// Caller creates context with span parent
HookContext ctx;
ctx.Set("otel_span_parent", std::make_shared<std::any>(span_context));
 
// Pass to variation method
client.BoolVariation(context, "flag-key", false, ctx);
 
// Hook accesses the span parent
auto span_parent = hook_context.Get("otel_span_parent");
