Struct Index 

pub struct Index { /* private fields */ }

SQLite-backed trace index. Cheap to construct; use one per process or thread.

Implementations

impl Index

pub fn open(path: impl AsRef<Path>) -> Result<Self>

Open (or create) a SQLite database at path. Applies the schema idempotently — safe to call on an existing DB.

pub fn open_in_memory() -> Result<Self>

Open an in-memory index (useful for tests).

pub fn register_trace(&mut self, trace: &TraceRecord) -> Result<()>

Register a trace. Existing rows with the same id are replaced (idempotent insert). Tags are cleared and re-inserted.

pub fn get_trace(&self, id: &str) -> Result<Option<TraceRecord>>

Look up a trace by id.

pub fn find_by_tag(&self, key: &str, value: &str) -> Result<Vec<String>>

Trace ids with tags.key = :key AND tags.value = :value.

pub fn find_by_session_tag(&self, tag: &str) -> Result<Vec<String>>

Trace ids with traces.session_tag = :tag.

pub fn recent(&self, limit: u32) -> Result<Vec<String>>

The limit most recently-created trace ids.

pub fn register_replay(&mut self, replay: &ReplayRecord) -> Result<()>

Register a replay.

pub fn replays_of(&self, baseline_trace_id: &str) -> Result<Vec<ReplayRecord>>

Replay records whose baseline is baseline_trace_id.
