Crate jetro 

Thin façade crate — re-exports jetro_core through the public Jetro API.

All parsing, optimisation, and execution live in jetro_core. This crate provides the byte-oriented Jetro handle plus JetroEngine for long-lived plan/VM reuse and NDJSON processing.

Modules

introspect

Opt-in query introspection.

io

Streaming input/output adapters for query execution.

Structs

EvalError

Evaluation error carrying a human-readable message. Propagated through Result<Val, EvalError> across all execution layers.

Jetro

Byte-oriented query handle. Wraps jetro_core::Jetro and exposes document parsing plus query collection.

JetroEngine

Long-lived multi-document query engine with an explicit plan cache. Use when the same process evaluates many expressions over many documents — parse/lower/compile work is amortised by this object, not hidden in thread-local state.

Enums

JetroEngineError

Error returned by JetroEngine::collect_bytes and similar methods that may fail during JSON parsing or during expression evaluation.
