# cue-rust `cue-rust` is a Rust-native implementation of the core CUE workflow. It includes a scanner, parser, compiler, evaluator, loader, encoders, public SDK, and a CLI binary named `cue`. Version `0.2.0` is useful for local evaluation, validation, data export, and Rust embedding. It is still intentionally narrower than the Go `cue` command: registry operations, LSP support, and full import/export parity for OpenAPI, JSON-Schema, Proto, and Go types are outside the stable surface today. ## Install From this repository: ```bash cargo install --path apps/cue --force cue version ``` During development: ```bash cargo run -p cue-rust-cli -- version ``` ## Quick Start Evaluate a CUE file: ```bash cue eval ./config.cue ``` Export concrete data: ```bash cue export --out json ./config.cue cue export --out yaml ./config.cue cue export --out toml ./config.cue ``` Validate data against a schema: ```bash cue vet ./schema.cue --data ./data.json ``` Use the SDK: ```rust use cue_rust::{Context, EvaluatedValue, Path, ValueExt}; let context = Context::new(); let value = context.compile_source( "example.cue", "app: { name: \"api\", port: *8080 | int }", )?; assert_eq!( EvaluatedValue::Number("8080".to_owned()), value .lookup(&Path::new().field("app").field("port"))? .default_value()? .evaluate()?, ); let json = value.to_json()?; assert!(json.contains("\"api\"")); # Ok::<(), Box<dyn std::error::Error>>(()) ``` ## Documentation English: - [User Guide](docs/guides/user-guide.md) - [Developer Guide](docs/guides/developer-guide.md) 中文： - [用户指南](docs/guides/user-guide.zh-CN.md) - [开发指南](docs/guides/developer-guide.zh-CN.md) More project documents are listed in [docs/index.md](docs/index.md). ## What Works In 0.2.0 - CUE scanning and tolerant parsing for the supported language subset - AST lowering into an ADT-style runtime - evaluation of structs, lists, defaults, disjunctions, references, constraints, comprehensions, interpolation, dynamic labels, closedness, and selected cycle behavior - local package loading, stdin, overlays, tags, external data files, and module-local imports under `cue.mod/pkg` - JSON, YAML, TOML, and CUE-like output - broad `strings`, `list`, and finite `math` builtin coverage - Rust SDK helpers for structured path lookup, default selection, validation, JSON export, and `serde_json::Value` export - CLI commands: `parse`, `eval`, `export`, `vet`, and `version` The current implementation is strict about source and decode limits, malformed number literals, local import paths, symlink inputs, escape handling, and exact numeric export for YAML/TOML. ## Current Limits Use the Go `cue` command when you need: - registry login, publish, or module proxy workflows - LSP/editor integration - complete upstream diagnostic wording parity - full OpenAPI, JSON-Schema, Proto/Protobuf, or Go type import/export - complete standard-library behavior for every upstream edge case For embedding, also note: - There is no `FillPath` or mutable value builder yet. Compose values by compiling inputs separately and calling `Value::unify`. - There is no direct typed decode into Rust structs. Export concrete values to JSON, then deserialize with `serde`. - There is no `Subsume` API yet. ## Development Common targets: ```bash make build make test make clippy-pedantic make vendor-corpus make compat-report make ci ``` Full local gate: ```bash make check make check-agent-sync make fuzz-smoke ``` `make check` runs workspace build, tests, nightly rustfmt check, pedantic clippy, docs, `cargo audit`, `cargo deny check`, and verified workspace packaging. ## License MIT.
