Struct OracleLayer

pub struct OracleLayer {
    pub oracle_puzzle_hash: Bytes32,
    pub oracle_fee: u64,
}

The Oracle Layer enables anyone to spend a coin provided they pay an XCH fee to an address. It’s typically used with DelegationLayer.

Fields

oracle_puzzle_hash: Bytes32

The puzzle hash corresponding to the address the fee should be paid to.

oracle_fee: u64

The amount of XCH that should be paid to the oracle.

Implementations

impl OracleLayer

pub fn new(oracle_puzzle_hash: Bytes32, oracle_fee: u64) -> Option<Self>

Creates a new OracleLayer if the fee is even. Returns None if the fee is odd, which would make the puzzle invalid.

impl OracleLayer

pub fn spend(self, ctx: &mut SpendContext) -> Result<Spend, DriverError>

Trait Implementations

impl Clone for OracleLayer

fn clone(&self) -> OracleLayer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OracleLayer

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

Formats the value using the given formatter.

impl Layer for OracleLayer

type Solution = ()

Most of the time, this is an actual CLVM type representing the solution. However, you can also use a helper struct and customize Layer::construct_solution and Layer::parse_solution.

fn parse_puzzle( allocator: &Allocator, puzzle: Puzzle, ) -> Result<Option<Self>, DriverError>

Parses this layer from the given puzzle, returning None if the puzzle doesn’t match. An error is returned if the puzzle should have matched but couldn’t be parsed.

fn parse_solution( _: &Allocator, _: NodePtr, ) -> Result<Self::Solution, DriverError>

Parses the Layer::Solution type from a CLVM solution pointer.

fn construct_puzzle( &self, ctx: &mut SpendContext, ) -> Result<NodePtr, DriverError>

Constructs the full curried puzzle for this layer. Ideally, the puzzle itself should be cached in the SpendContext.

fn construct_solution( &self, _: &mut SpendContext, (): Self::Solution, ) -> Result<NodePtr, DriverError>

Constructs the full solution for this layer. Can be used to construct the solution from a helper struct, if it’s not directly a CLVM type. It’s also possible to influence the solution based on the puzzle, if needed.

fn construct_spend( &self, ctx: &mut SpendContext, solution: Self::Solution, ) -> Result<Spend, DriverError>

Creates a spend for this layer.

fn construct_coin_spend( &self, ctx: &mut SpendContext, coin: Coin, solution: Self::Solution, ) -> Result<CoinSpend, DriverError>

Creates a coin spend for this layer.

impl PartialEq for OracleLayer

fn eq(&self, other: &OracleLayer) -> 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.
