Struct WasmtimeConfig 

pub struct WasmtimeConfig {
    pub memory_config: MemoryConfig,
    pub strategy: InstanceAllocationStrategy,
    pub compiler_strategy: CompilerStrategy,
    pub async_config: AsyncConfig,
    /* private fields */
}

Configuration related to wasmtime::Config and the various settings which can be tweaked from within.

Fields

memory_config: MemoryConfig

The Wasmtime memory configuration to use.

strategy: InstanceAllocationStrategy

Configuration for the instance allocation strategy to use.

compiler_strategy: CompilerStrategy

Configuration for the compiler to use.

async_config: AsyncConfig

Configuration for whether wasm is invoked in an async fashion and how it’s cooperatively time-sliced.

Implementations

impl WasmtimeConfig

pub fn make_compatible_with(&mut self, other: &Self)

Force self to be a configuration compatible with other. This is useful for differential execution to avoid unhelpful fuzz crashes when one engine has a feature enabled and the other does not.

pub fn update_module_config( &mut self, config: &mut ModuleConfig, _u: &mut Unstructured<'_>, ) -> Result<()>

Updates config to be compatible with self and the other way around too.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for WasmtimeConfig

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

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

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

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.

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

impl Clone for WasmtimeConfig

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WasmtimeConfig
