drmkit-log

drmkit's library-wide diagnostic surface. Two knobs, matching drm-cxx's:

1. set_log_level — process-wide threshold. Records at or below the active level are emitted; the rest are dropped before formatting cost is paid. A call below the threshold reduces to one relaxed atomic load and a branch.

2. set_log_sink — process-wide redirection hook. The default sink writes to stderr (errors, warnings) or stdout (info, debug) prefixed with [drm:LEVEL] . Consumers can forward to tracing, journald, syslog, or an in-memory test buffer. reset_log_sink restores the default — the Rust spelling of the C++ set_log_sink(nullptr) path.

Part of drmkit, a Rust port of drm-cxx. API documentation is on docs.rs.
