Implementations

impl WasmComponent

pub async fn convert_core_module_to_component( wasm_path: &Path, input_content_digest: &ContentDigest, output_parent: &Path, ) -> Result<Option<PathBuf>, Error>

Convert input WASM file to a Component. Return Ok(Some(output_path)) if conversion was successful. Output path is constructed as {output_parent}/sha256_{input_digest}_transformed.wasm . If the output path already exists, the conversion is skipped as it is assumed that Obelisk has made the transformation. Return Ok(None) if the input file is a Component.

pub fn verify_wasm(wasm_path: impl AsRef<Path>) -> Result<(), DecodeError>

Attempt to open the WASM file, parse it using wit_parser. Check that the file is a WASM Component.

pub fn new( wasm_path: impl AsRef<Path>, component_type: ComponentType, ) -> Result<Self, DecodeError>

pub fn new_from_wit_string( wit: &str, component_type: ComponentType, ) -> Result<Self, DecodeError>

Create a WasmComponent from a WIT string (no WASM binary). Used for JS workflows/activities where the user interface is synthesized.

pub fn new_from_fn_signature( ffqn: &FunctionFqn, params: &[ParameterType], return_type: &ReturnTypeExtendable, component_type: ComponentType, world_name: &str, ) -> Result<Self, DecodeError>

Create a WasmComponent directly from a function signature, bypassing WIT text synthesis and re-parsing. Used for JS activities/workflows/stubs where we already have all the type information and don’t need the WIT text roundtrip that new_from_wit_string performs.

pub fn new_from_wit_folder( path: impl AsRef<Path>, component_type: ComponentType, ) -> Result<Self, DecodeError>

pub fn exported_functions(&self, extensions: bool) -> &[FunctionMetadata]

pub fn imported_functions(&self) -> &[FunctionMetadata]

pub fn wit(&self) -> String

Return the WIT text for this component, including obelisk extension packages.

Cannot fail: every constructor calls rebuild_resolve which already proves the stored resolve is printable, so WitPrinter::print on it a second time is infallible.

pub fn exports_hierarchy_ext(&self) -> &[PackageIfcFns]

pub fn exported_extension_wits(&self) -> Result<HashMap<PkgFqn, String>, Error>
