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.

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 WasmtimeConfig

fn clone(&self) -> WasmtimeConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WasmtimeConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for WasmtimeConfig

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for WasmtimeConfig

fn eq(&self, other: &WasmtimeConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
