Enum money::MoneyConstraintChecker

pub enum MoneyConstraintChecker<const ID: u8> {
    Spend,
    Mint,
}

The main constraint checker for the money piece. Allows spending and minting tokens.

Variants

Spend

A typical spend transaction where some coins are consumed and others are created. Input value must exceed output value. The difference is burned and reflected in the transaction’s priority.

Mint

A mint transaction that creates no coins out of the void. In a real-world chain, this should be protected somehow, or not included at all. For now it is publicly available. I’m adding it to explore multiple validation paths in a single piece.

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<const ID: u8> Encode for MoneyConstraintChecker<ID>

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl<const ID: u8> Hash for MoneyConstraintChecker<ID>

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<const ID: u8> Ord for MoneyConstraintChecker<ID>

fn cmp(&self, other: &MoneyConstraintChecker<ID>) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl<const ID: u8> PartialEq for MoneyConstraintChecker<ID>

fn eq(&self, other: &MoneyConstraintChecker<ID>) -> bool

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<const ID: u8> PartialOrd for MoneyConstraintChecker<ID>

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl<const ID: u8> Serialize for MoneyConstraintChecker<ID>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<const ID: u8> SimpleConstraintChecker for MoneyConstraintChecker<ID>

type Error = ConstraintCheckerError

The error type that this constraint checker may return

fn check( &self, input_data: &[DynamicallyTypedData], evicted_input_data: &[DynamicallyTypedData], _peeks: &[DynamicallyTypedData], output_data: &[DynamicallyTypedData] ) -> Result<TransactionPriority, Self::Error>

The on chain logic that makes the final check for whether a transaction is valid.

impl<const ID: u8> TypeInfo for MoneyConstraintChecker<ID>

type Identity = MoneyConstraintChecker<ID>

The type identifying for which type info is provided.

fn type_info() -> Type

Returns the static type identifier for Self.
