Struct WasmV2Config

pub struct WasmV2Config { /* private fields */ }

Available on crate feature std only.

Configuration of the Wasm execution environment for V2 execution machine.

This structure contains various Wasm execution configuration options, such as memory limits and costs.

Implementations

impl WasmV2Config

pub fn new( max_memory: u32, opcode_costs: OpcodeCosts, host_function_costs: HostFunctionCostsV2, ) -> Self

ctor

pub fn opcode_costs(&self) -> OpcodeCosts

Returns opcode costs.

pub fn host_function_costs(&self) -> &HostFunctionCostsV2

Returns a reference to host function costs

pub fn take_host_function_costs(self) -> HostFunctionCostsV2

Returns host function costs and consumes this object.

pub fn max_memory(&self) -> u32

Returns max_memory.

pub fn max_memory_mut(&mut self) -> &mut u32

Available on crate feature testing only.

Returns mutable max_memory reference

Trait Implementations

impl Clone for WasmV2Config

fn clone(&self) -> WasmV2Config

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSize for WasmV2Config

const IS_DYNAMIC: bool = false

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for WasmV2Config

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

Formats the value using the given formatter.

impl Default for WasmV2Config

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WasmV2Config

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Distribution<WasmV2Config> for Standard

Available on crate feature testing only.

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> WasmV2Config

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T>

where R: Rng, Self: Sized,

Create an iterator that generates random values of T, using rng as the source of randomness.

fn map<F, S>(self, func: F) -> DistMap<Self, F, T, S>

where F: Fn(T) -> S, Self: Sized,

Create a distribution of values of ‘S’ by mapping the output of Self through the closure F

impl FromBytes for WasmV2Config

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl PartialEq for WasmV2Config

fn eq(&self, other: &WasmV2Config) -> 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.

impl Serialize for WasmV2Config

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToBytes for WasmV2Config

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn into_bytes(self) -> Result<Vec<u8>, Error>

where Self: Sized,

Consumes self and serializes to a Vec<u8>.

fn write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.
