pub struct WasmtimeEngine { /* private fields */ }Expand description
A wrapper for using Wasmtime as a DiffEngine.
Implementations§
Source§impl WasmtimeEngine
impl WasmtimeEngine
Sourcepub fn new(
u: &mut Unstructured<'_>,
config: &mut Config,
compiler_strategy: CompilerStrategy,
) -> Result<Self>
pub fn new( u: &mut Unstructured<'_>, config: &mut Config, compiler_strategy: CompilerStrategy, ) -> Result<Self>
Merely store the configuration; the engine is actually constructed
later. Ideally the store and engine could be built here but
compile_module takes a generators::Config; TODO re-factor this if
that ever changes.
Trait Implementations§
Source§impl DiffEngine for WasmtimeEngine
impl DiffEngine for WasmtimeEngine
Source§fn instantiate(&mut self, wasm: &[u8]) -> Result<Box<dyn DiffInstance>>
fn instantiate(&mut self, wasm: &[u8]) -> Result<Box<dyn DiffInstance>>
Create a new instance with the given engine.
Source§fn assert_error_match(&self, lhs: &Error, rhs: &Trap)
fn assert_error_match(&self, lhs: &Error, rhs: &Trap)
Tests that the wasmtime-originating
trap matches the error this engine
generated.Source§fn is_non_deterministic_error(&self, err: &Error) -> bool
fn is_non_deterministic_error(&self, err: &Error) -> bool
Returns whether the error specified from this engine is
non-deterministic, like a stack overflow or an attempt to allocate an
object that is too large (which is non-deterministic because it may
depend on which collector it was configured with or memory available on
the system).

downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Converts
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
