rustlavel-search

Elasticsearch and OpenSearch for Rustlavel: indexing, search, and bulk operations.

Part of Rustlavel, a full-stack web framework for Rust written from scratch — no Axum, no hyper, no SeaORM. Tokio is the only large dependency.

Using it

Enable it through the meta-crate rather than depending on this one directly, so the versions stay in step:

[dependencies]
rustlavel = { version = "0.9", features = ["search"] }

Shipping logs

Every info!, warn! and error! is an event on the framework's bus, so shipping logs to the cluster is a subscriber. It writes one document per line to a daily index (logs-2026.10.21), shaped after the Elastic Common Schema's common fields, in batches, with a bounded queue that drops the newest line and counts it rather than slowing a request.

# config/search.json
{ "url": "http://localhost:9200", "logs": { "enabled": true, "index": "logs" } }

App::new()?.plugin(rustlavel::search::LogShipping::default()).run().await

Off unless search.logs.enabled is true. Flushed when the server shuts down. Verified against Elasticsearch 8.15 and OpenSearch 2.17.
