Struct wasm_smith::SwarmConfig

pub struct SwarmConfig { /* fields omitted */ }

A module configuration that uses swarm testing.

Dynamically -- but still deterministically, via its Arbitrary implementation -- chooses configuration options.

Trait Implementations

impl Arbitrary for SwarmConfig

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

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

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

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

pub 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.

pub fn shrink(&self) -> Box<dyn Iterator<Item = Self> + 'static, Global>

Generate an iterator of derived values which are "smaller" than the original self instance.

impl Clone for SwarmConfig

pub fn clone(&self) -> SwarmConfig

Returns a copy of the value.

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

Performs copy-assignment from source.
