Enum RefundHandling

pub enum RefundHandling {
    Refund {
        refund_ratio: Ratio<u64>,
    },
    Burn {
        refund_ratio: Ratio<u64>,
    },
    NoRefund,
}

Available on crate feature std only.

Defines how refunds are calculated.

Variants

Refund

Refund of excess payment amount goes to either a pre-defined purse, or back to the sender and the rest of the payment amount goes to the block proposer.

Fields

refund_ratio: Ratio<u64>

Computes how much refund goes back to the user after deducting gas spent from the paid amount.

user_part = (payment_amount - gas_spent_amount) * refund_ratio validator_part = payment_amount - user_part

Any dust amount that was a result of multiplying by refund_ratio goes back to user.

Burn

Burns the refund amount.

Fields

refund_ratio: Ratio<u64>

Computes how much of the refund amount is burned after deducting gas spent from the paid amount.

NoRefund

No refunds.

Implementations

impl RefundHandling

pub fn skip_refund(&self) -> bool

Returns true if we don’t need to process a refund.

pub fn refund_ratio(&self) -> Ratio<u64>

Returns refund ratio.

Trait Implementations

impl Clone for RefundHandling

fn clone(&self) -> RefundHandling

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RefundHandling

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

Formats the value using the given formatter.

impl Default for RefundHandling

fn default() -> RefundHandling

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RefundHandling

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromBytes for RefundHandling

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 RefundHandling

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

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 RefundHandling

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.
