Struct Journal 

pub struct Journal { /* private fields */ }

Implementations

impl Journal

pub async fn query(&self, filter: JournalFilter) -> Result<JournalResult>

Query journald logs using the configured backend.

Default backend: sdjournal (feature=journal-sdjournal). Alternative backend: journalctl --output=json (feature=journal-cli).

The result is always bounded by filter.limit and filter.max_bytes. When limits are hit, JournalResult.truncated is set to true.

pub async fn diagnose_unit_failure( &self, unit: &str, opts: DiagnosisOptions, ) -> Result<Diagnosis>

Convenience helper that fetches a status snapshot and a bounded log slice around “now”.

The default time window is now - 30s to now + 10s (see DiagnosisOptions::default).
