Implementations

impl WasmConfig

pub const fn new(
    max_memory: u32,
    max_stack_height: u32,
    opcode_costs: OpcodeCosts,
    storage_costs: StorageCosts,
    host_function_costs: HostFunctionCosts
) -> Self

pub fn opcode_costs(&self) -> OpcodeCosts

pub fn storage_costs(&self) -> StorageCosts

pub fn take_host_function_costs(self) -> HostFunctionCosts

Trait Implementations

impl Clone for WasmConfig

pub fn clone(&self) -> WasmConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for WasmConfig

impl DataSize for WasmConfig

pub const IS_DYNAMIC: bool

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

pub const STATIC_HEAP_SIZE: usize

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.

pub fn estimate_heap_size(&self) -> usize

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

impl Debug for WasmConfig

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

Formats the value using the given formatter.

impl Default for WasmConfig

pub fn default() -> Self

Returns the "default value" for a type.

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

pub 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

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

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

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

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

impl Eq for WasmConfig

impl FromBytes for WasmConfig

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

Deserializes the slice into Self.

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

Deserializes the Vec<u8> into Self.

impl PartialEq<WasmConfig> for WasmConfig

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Serialize for WasmConfig

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

Serialize this value into the given Serde serializer.

impl StructuralEq for WasmConfig

impl StructuralPartialEq for WasmConfig

impl ToBytes for WasmConfig

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

Serializes &self to a Vec<u8>.

pub 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.

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

Consumes self and serializes to a Vec<u8>.
