Struct WasmConfig

pub struct WasmConfig { /* private fields */ }

Available on crate feature std only.

Configuration of the Wasm execution environment.

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

Implementations

impl WasmConfig

pub const fn new( messages_limits: MessageLimits, v1: WasmV1Config, v2: WasmV2Config, ) -> Self

Creates new Wasm config.

pub fn messages_limits(&self) -> MessageLimits

Returns the limits config for messages.

pub fn v1(&self) -> &WasmV1Config

Returns the config for v1 wasms.

pub fn v1_mut(&mut self) -> &mut WasmV1Config

Available on crate feature testing only.

Returns mutable v1 reference

pub fn v2(&self) -> &WasmV2Config

Returns the config for v2 wasms.

pub fn v2_mut(&mut self) -> &mut WasmV2Config

Available on crate feature testing only.

Returns mutable v2 reference

Trait Implementations

impl Clone for WasmConfig

fn clone(&self) -> WasmConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSize for WasmConfig

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 WasmConfig

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

Formats the value using the given formatter.

impl Default for WasmConfig

fn default() -> WasmConfig

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WasmConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Distribution<WasmConfig> for Standard

Available on crate feature testing only.

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

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 WasmConfig

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 WasmConfig

fn eq(&self, other: &WasmConfig) -> 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 WasmConfig

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 WasmConfig

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.
