¶Logging

elyra::log is the framework's Log facade: levels, targets, timestamps, and an optional rotating file sink.

use elyra::{info, warn, error};

info!("sync finished in {}ms", elapsed);
warn!(target: "sync", "retrying: {e}");
error!("import failed: {e}");

¶Configuration

use elyra::log::{Level, LogProvider};

App::new().provider(
    LogProvider::new()
        .level(Level::Debug)
        .to_app_dir("My App")      // <config>/<app>/app.log
        .rotate(5 * 1024 * 1024, 3) // 5 MiB, keep 3 files
)

ELYRA_LOG overrides the level at runtime (error/warn/info/debug/trace, or off) — the same reflex as RUST_LOG.

elyra::log::log_path() returns the active file, which is what a "send us your log" button should attach.

¶What the framework logs

• every command dispatch at debug: name, byte sizes, duration
• command failures at warn, panics at error (with the panic message)
• tray/shortcut/updater setup problems at warn/error
• migrations and seeding at info
