Gradle Task Reference

All tasks live in the default Gradle task group and run in strict dependency order. They are registered only when enabled is true.

`kreate-c-interop-initialize`

Class: InitializeRustProject

Runs cargo new --lib <projectName> inside projectDirectory. If the target directory already exists, the task is a no-op — it will not overwrite your existing Rust source files.

Input	Description
`workDir`	The resolved `projectDirectory`
`projectName`	The resolved project name

Output	Description
`outputDir`	`<workDir>/<projectName>/`

`kreate-c-interop-dependencies`

Class: AddRustDependencies

Adds runtime and build dependencies to Cargo.toml via cargo add. Defaults to adding libc as a runtime dependency and cbindgen as a build dependency. Already-present dependencies are skipped automatically by checking the current Cargo.toml content before invoking cargo add.

Input	Description
`workDir`	The Rust project directory
`rustDependencies`	Map of `name → version`; defaults to `{"libc": ""}`
`rustBuildDependencies`	Map of `name → version`; defaults to `{"cbindgen": ""}`

`kreate-c-interop-configure`

Class: ConfigureCargo

Appends the following block to Cargo.toml if not already present:

[lib]
crate-type = ["staticlib"]

This ensures Cargo produces a static library (.a/.lib) suitable for linking into Kotlin/Native. If the block is already present, the task is a no-op.

Input	Description
`workDir`	The Rust project directory containing `Cargo.toml`

Output	Description
`outputFile`	`<workDir>/Cargo.toml`

`kreate-c-interop-script`

Class: GenerateRustBuildScript

Creates build.rs in the Rust project root. The script uses cbindgen to generate a C header at include/<projectName>.h. If build.rs already exists and is non-empty, the task is skipped.

Input	Description
`workDir`	The Rust project directory
`projectName`	Used as the header file name inside the generated script

Output	Description
`outputFile`	`<workDir>/build.rs`

`kreate-c-interop-compile`

Class: CompileRust

Executes cargo build --target <target> --release for each resolved Rust target in sequence. If compilation fails for any target, a GradleException is thrown immediately with the failing target name.

Input	Description
`workDir`	The Rust project directory
`rustTargets`	Optional; resolved from config or auto-detected from host OS/arch

Output	Description
`outputDir`	`<workDir>/target/`

`kreate-c-interop-definitions`

Class: GenerateDefinitionFiles

Creates the directory specified by defDirName and writes the .def file consumed by CInteropProcess. The file references the compiled static library and the generated C header. This task always rewrites the .def file — it is not incrementally skipped.

Input	Description
`workDir`	The Rust project directory
`rootDir`	The `projectDirectory` (parent of the Rust project)
`projectName`	Used in header and library names
`defFileName`	File name for the `.def` file
`defDirName`	Directory name for the `.def` file
`rustTargets`	Optional; used to construct the `libraryPaths` entries

Output	Description
`outputDir`	`<workDir>/<defDirName>/`
