Enum PricingMode

pub enum PricingMode {
    PaymentLimited {
        payment_amount: u64,
        gas_price_tolerance: u8,
        standard_payment: bool,
    },
    Fixed {
        additional_computation_factor: u8,

    },
    Prepaid {
        receipt: Digest,
    },
}

The pricing mode of a Transaction.

Variants

PaymentLimited

The original payment model, where the creator of the transaction specifies how much they will pay, at what gas price.

Fields

payment_amount: u64

User-specified payment amount.

gas_price_tolerance: u8

User-specified gas_price tolerance (minimum 1). This is interpreted to mean “do not include this transaction in a block if the current gas price is greater than this number”

standard_payment: bool

Standard payment.

Fixed

The cost of the transaction is determined by the cost table, per the transaction category.

Fields

additional_computation_factor: u8

User-specified additional computation factor (minimum 0). If “0” is provided, no additional logic is applied to the computation limit. Each value above “0” tells the node that it needs to treat the transaction as if it uses more gas than it’s serialized size indicates. Each “1” will increase the “wasm lane” size bucket for this transaction by 1. So if the size of the transaction indicates bucket “0” and “additional_computation_factor = 2”, the transaction will be treated as a “2”.

gas_price_tolerance: u8

User-specified gas_price tolerance (minimum 1). This is interpreted to mean “do not include this transaction in a block if the current gas price is greater than this number”

Prepaid

The payment for this transaction was previously paid, as proven by the receipt hash (this is for future use, not currently implemented).

Fields

receipt: Digest

Pre-paid receipt.

Implementations

impl PricingMode

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

Available on crate feature testing only.

Returns a random `PricingMode.

pub fn is_standard_payment(&self) -> bool

Returns standard payment flag, if it is a PaymentLimited variant.

pub fn gas_limit( &self, chainspec: &Chainspec, lane_id: u8, ) -> Result<Gas, PricingModeError>

Available on crate feature std only.

Returns the gas limit.

pub fn gas_cost( &self, chainspec: &Chainspec, lane_id: u8, gas_price: u8, ) -> Result<Motes, PricingModeError>

Available on crate feature std only.

Returns gas cost.

pub fn additional_computation_factor(&self) -> u8

Returns gas cost.

Trait Implementations

impl Clone for PricingMode

fn clone(&self) -> PricingMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSize for PricingMode

const IS_DYNAMIC: bool = true

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 PricingMode

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

Formats the value using the given formatter.

impl Default for PricingMode

Available on crate feature testing only.

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PricingMode

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PricingMode

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

Formats the value using the given formatter.

impl FromBytes for PricingMode

fn from_bytes(bytes: &[u8]) -> Result<(PricingMode, &[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 Hash for PricingMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl JsonSchema for PricingMode

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Ord for PricingMode

fn cmp(&self, other: &PricingMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PricingMode

fn eq(&self, other: &PricingMode) -> 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 PartialOrd for PricingMode

fn partial_cmp(&self, other: &PricingMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for PricingMode

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 PricingMode

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>
