Struct SystemConfig

pub struct SystemConfig { /* private fields */ }

Available on crate feature std only.

Definition of costs in the system.

This structure contains the costs of all the system contract’s entry points and, additionally, it defines a wasmless mint cost.

Implementations

impl SystemConfig

pub fn new( no_such_entrypoint: u64, auction_costs: AuctionCosts, mint_costs: MintCosts, handle_payment_costs: HandlePaymentCosts, standard_payment_costs: StandardPaymentCosts, ) -> Self

Creates new system config instance.

pub fn no_such_entrypoint(&self) -> u64

Returns the cost of calling a non-existing system contract entry point.

pub fn auction_costs(&self) -> &AuctionCosts

Returns the costs of executing auction entry points.

pub fn mint_costs(&self) -> &MintCosts

Returns the costs of executing mint entry points.

pub fn with_mint_costs(self, mint_costs: MintCosts) -> Self

Sets mint costs.

pub fn handle_payment_costs(&self) -> &HandlePaymentCosts

Returns the costs of executing handle_payment entry points.

pub fn standard_payment_costs(&self) -> &StandardPaymentCosts

Returns the costs of executing standard_payment entry points.

impl SystemConfig

pub fn random(rng: &mut TestRng) -> Self

Available on crate feature testing only.

Generates a random instance using a TestRng.

Trait Implementations

impl Clone for SystemConfig

fn clone(&self) -> SystemConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DataSize for SystemConfig

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 SystemConfig

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

Formats the value using the given formatter.

impl Default for SystemConfig

fn default() -> Self

Implements Default for SystemConfig.

impl<'de> Deserialize<'de> for SystemConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Distribution<SystemConfig> for Standard

Available on crate feature testing only.

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

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 SystemConfig

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 SystemConfig

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

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 SystemConfig

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.
