Enum FeeHandling

pub enum FeeHandling {
    PayToProposer,
    Accumulate,
    Burn,
    NoFee,
}

Available on crate feature std only.

Defines how fees are handled in the system.

Variants

PayToProposer

Transaction fees are paid to the block proposer.

This is the default option for public chains.

Accumulate

Transaction fees are accumulated in a special purse and then distributed during end of era processing evenly among all administrator accounts.

This setting is applicable for some private chains (but not all).

Burn

Burn the fees.

NoFee

No fees.

Implementations

impl FeeHandling

pub fn is_accumulate(&self) -> bool

Is the Accumulate variant selected?

pub fn is_no_fee(&self) -> bool

Returns true if configured for no fees.

Trait Implementations

impl Clone for FeeHandling

fn clone(&self) -> FeeHandling

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSize for FeeHandling

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 FeeHandling

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

Formats the value using the given formatter.

impl Default for FeeHandling

fn default() -> FeeHandling

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FeeHandling

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromBytes for FeeHandling

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 FeeHandling

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

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 FeeHandling

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.
