Struct WastContext

pub struct WastContext { /* private fields */ }

The wast test script language allows modules to be defined and actions to be performed on them.

Implementations

impl WastContext

pub fn new( engine: &Engine, async_: Async, configure: impl Fn(&mut Store<()>) + Send + Sync + 'static, ) -> Self

Construct a new instance of WastContext.

The engine provided is used for all store/module/component creation and should be appropriately configured by the caller. The async_ configuration indicates whether functions are invoked either async or sync, and then the configure callback is used whenever a store is created to further configure its settings.

pub fn precompile_save(&mut self, path: impl AsRef<Path>) -> &mut Self

Saves precompiled modules/components into path instead of executing test directives.

pub fn precompile_load(&mut self, path: impl AsRef<Path>) -> &mut Self

Loads precompiled modules/components from path instead of compiling natively.

pub fn register_spectest(&mut self, config: &SpectestConfig) -> Result<()>

Register “spectest” which is used by the spec testsuite.

pub fn run_wast(&mut self, filename: &str, wast: &[u8]) -> Result<()>

Run a wast script from a byte buffer.

pub fn run_file(&mut self, path: &Path) -> Result<()>

Run a wast script from a file.

pub fn generate_dwarf(&mut self, enable: bool) -> &mut Self

Whether or not to generate DWARF debugging information in custom sections in modules being tested.
