Struct ModuleConfig

pub struct ModuleConfig {
    pub config: Config,
    pub function_references_enabled: bool,
    pub component_model_async: bool,
}

Default module-level configuration for fuzzing Wasmtime.

Internally this uses wasm-smith’s own Config but we further refine the defaults here as well.

Fields

config: Config

function_references_enabled: bool

component_model_async: bool

Implementations

impl ModuleConfig

pub fn generate( &self, input: &mut Unstructured<'_>, default_fuel: Option<u32>, ) -> Result<Module>

Uses this configuration and the supplied source of data to generate a Wasm module.

If a default_fuel is provided, the resulting module will be configured to ensure termination; as doing so will add an additional global to the module, the pooling allocator, if configured, must also have its globals limit updated.

Trait Implementations

impl<'a> Arbitrary<'a> for ModuleConfig

fn arbitrary(u: &mut Unstructured<'a>) -> Result<ModuleConfig>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for ModuleConfig

fn clone(&self) -> ModuleConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ModuleConfig
