Crate cljrs_logging 

Feature-gated logging for clojurust.

Provides per-feature debug and trace logging controlled at runtime via CLI flags. Features are arbitrary strings (e.g. “gc”, “jit”, “reader”) — any feature name is accepted even if no code ever logs with it.

Usage

// Set features from CLI flags
cljrs_logging::set_feature_level("gc", Level::Debug);
cljrs_logging::set_feature_level("jit", Level::Trace);

// In code:
feat_debug!("gc", "starting collection, heap_size={}", heap_size);
feat_trace!("gc", "visiting object at {:p}", ptr);
