// Package noop provides an implementation of the [OpenTelemetry Logs Bridge
// API] that produces no telemetry and minimizes used computation resources.
//
// Using this package to implement the [OpenTelemetry Logs API] will
// effectively disable OpenTelemetry.
//
// This implementation can be embedded in other implementations of the
// [OpenTelemetry Logs API]. Doing so will mean the implementation
// defaults to no operation for methods it does not implement.
