gl-sdk

Rust SDK for Greenlight with UniFFI bindings support.

Building

Build the library using Task:

task sdk:build

Or directly with cargo from the workspace root:

cd /home/cdecker/dev/greenlight/202509-sdk/public
cargo build -p gl-sdk

Generating Language Bindings

Using Task (Recommended)

The easiest way to generate bindings is using the Task commands:

# Generate Python bindings
task sdk:bindings-python

# Generate Kotlin bindings
task sdk:bindings-kotlin

# Generate Swift bindings
task sdk:bindings-swift

# Generate Ruby bindings
task sdk:bindings-ruby

# Generate all language bindings
task sdk:bindings-all

These commands work from any directory in the workspace.

Using uniffi-bindgen Directly

The project uses UniFFI to generate bindings for multiple languages from the UDL definition in src/sdk.udl.

The uniffi-bindgen tool is included in the workspace at libs/uniffi-bindgen.

Note: When using uniffi-bindgen directly, all commands must be run from the workspace root.

Generate Python Bindings

cd /home/cdecker/dev/greenlight/202509-sdk/public
cargo run --bin uniffi-bindgen -- generate \
  --library $CARGO_TARGET_DIR/debug/libglsdk.so \
  --language python \
  --out-dir ./libs/gl-sdk/bindings

Generate Bindings for Other Languages

Replace --language python with:

• kotlin for Kotlin
• swift for Swift
• ruby for Ruby

Example for Kotlin:

cargo run --bin uniffi-bindgen -- generate \
  --library $CARGO_TARGET_DIR/debug/libglsdk.so \
  --language kotlin \
  --out-dir ./libs/gl-sdk/bindings
