Use workspace dependencies & settings

[ladvoc]

Use the workspace-level Cargo.toml as the single source of truth for shared metadata (such as Rust edition and license) and for common dependencies to avoid version fragmentation across crates.

📝 Walkthrough

Walkthrough

This pull request consolidates Cargo dependency management by introducing a workspace-level configuration with shared versions and metadata, then converting all example crates and libraries across the repository to use workspace-scoped dependencies instead of per-crate version pinning.

Changes

Cohort / File(s)	Summary
Root Workspace Configuration Cargo.toml	Introduces new [workspace.package] section with edition, repository, and license; adds comprehensive [workspace.dependencies] with versions for ~30 common dependencies (anyhow, bytes, clap, tokio, serde, etc.); extends [profile.release] with optimization settings (codegen-units, panic, strip, debug).
Example Crate Dependencies examples/agent_dispatch/Cargo.toml, examples/api/Cargo.toml, examples/basic_room/Cargo.toml, examples/basic_text_stream/Cargo.toml, examples/encrypted_text_stream/Cargo.toml, examples/local_audio/Cargo.toml, examples/local_video/Cargo.toml, examples/mobile/Cargo.toml, examples/play_from_disk/Cargo.toml, examples/rpc/Cargo.toml, examples/save_to_disk/Cargo.toml, examples/screensharing/Cargo.toml, examples/send_bytes/Cargo.toml, examples/webhooks/Cargo.toml, examples/wgpu_room/Cargo.toml	Convert edition to edition.workspace = true and replace explicit dependency versions with workspace = true references; preserve existing feature flags across all crates.
Core Library Dependencies libwebrtc/Cargo.toml, livekit-api/Cargo.toml, livekit-ffi/Cargo.toml, livekit-protocol/Cargo.toml, livekit-runtime/Cargo.toml, livekit-uniffi/Cargo.toml, livekit/Cargo.toml	Migrate edition, license, and repository fields to workspace-scoped references; convert all dependencies (tokio, serde, log, futures-util, etc.) from versioned specs to workspace = true while maintaining feature selections.
Build & FFI System Crates livekit-ffi-node-bindings/Cargo.toml, webrtc-sys/Cargo.toml, webrtc-sys/build/Cargo.toml, soxr-sys/Cargo.toml, yuv-sys/Cargo.toml, imgproc/Cargo.toml	Switch edition, license, and repository to workspace-scoped declarations; convert dependencies to workspace-managed references; webrtc-sys adds explicit build-dependencies (cxx-build, glob, cc) alongside workspace-backed entries.

🔇 Additional comments (36)

imgproc/Cargo.toml (1)

4-6: LGTM!

The workspace edition inheritance is correctly configured. Note that license remains explicitly set here while some other crates in this PR use license.workspace = true — this appears intentional if this crate maintains its own licensing terms.

livekit-uniffi/Cargo.toml (1)

7-10: LGTM!

The workspace metadata and dependency migrations are correctly implemented. The tokio dependency appropriately specifies only the ["sync"] feature needed by this crate while inheriting the version from the workspace.

Also applies to: 18-19

yuv-sys/Cargo.toml (1)

4-4: LGTM!

The workspace edition inheritance is correctly configured. Build dependencies remaining with explicit versions is reasonable for this sys crate.

examples/save_to_disk/Cargo.toml (1)

4-4: LGTM!

The workspace migrations are correctly implemented for this example crate. The tokio dependency appropriately retains the ["full"] feature set needed for the example.

Also applies to: 8-11

examples/send_bytes/Cargo.toml (1)

4-4: LGTM!

The workspace migrations are correctly implemented. Dependencies specific to this example (bitfield-struct, colored) appropriately remain with explicit versions.

Also applies to: 8-8, 10-11, 13-13

examples/rpc/Cargo.toml (1)

4-4: LGTM!

The workspace migrations are correctly implemented for this example crate, consistent with the patterns used in other examples.

Also applies to: 8-9, 12-14

soxr-sys/Cargo.toml (1)

5-6: LGTM!

The workspace edition and license inheritance are correctly configured.

examples/play_from_disk/Cargo.toml (1)

livekit-protocol/Cargo.toml (1)

4-23: Workspace inheritance is properly configured.

Verification confirms that [workspace.package] defines edition, license, and repository, and [workspace.dependencies] defines all referenced dependencies (tokio, futures-util, parking_lot, serde, thiserror, livekit-runtime). The build will succeed without errors.

---

4-4: The workspace package metadata is properly defined in the root Cargo.toml with [workspace.package] section containing edition, license, and repository fields. Switching to *.workspace = true in libwebrtc/Cargo.toml is safe and will not cause manifest resolution errors.

examples/webhooks/Cargo.toml (1)

Also applies to: 15-15, 28-28

livekit-ffi/Cargo.toml (1)

Also applies to: 27-33, 35-35, 37-38, 46-46

examples/wgpu_room/Cargo.toml (1)

4-4: LGTM: workspace metadata and dependency consolidation.

Also applies to: 12-12, 15-15, 17-17, 23-26

livekit-api/Cargo.toml (5)

4-7: Workspace package metadata is properly defined.

The workspace manifest correctly defines license (Apache-2.0), edition (2021), and repository (https://github.com/livekit/rust-sdks), so inheriting these in livekit-api/Cargo.toml lines 4–7 is safe for builds and publishing.

---

104-104: No action required. The workspace rand version is 0.9, which is compatible with all API usage in the crate (rand::Rng, rand::rng(), and .random::<u8>()). Using { workspace = true } maintains compatibility with the workspace specification.

---

73-78: Workspace dependency entries confirmed present and correctly composed.

All four dependencies are properly defined in the workspace manifest:

• thiserror = "1"
• serde = "1" (features added per-crate as needed)
• log = "0.4"
• parking_lot = "0.12"

The serde feature specification in livekit-api (features = ["derive"]) correctly layers on top of the workspace version without conflicts.

---

83-83: Workspace serde_json configuration is correct for webhook payload handling.

The workspace definition (serde_json = "1.0") provides all required functionality. Webhook deserialization only uses basic serde_json::from_str() parsing, which requires no special features beyond the default feature set. The optional dependency in livekit-api is appropriately gated behind the webhooks feature.

---

93-96: Workspace tokio/futures-util configuration is compatible.

The workspace versions (tokio = "1", futures-util = "0.3") align with the requested features (sync, macros, signal, io-util, net, sink). All specified features are valid for these versions. The explicit default-features = false with feature selection is correct.
