Struct P2ControllerPuzzleLayer 

pub struct P2ControllerPuzzleLayer {
    pub controller_puzzle_hash: Bytes32,
}

The CHIP-0037 controller-puzzle Layer.

Locks a coin so it can only be spent when a coin whose puzzle hash equals controller_puzzle_hash sends a RECEIVE_MESSAGE whose body is the tree hash of the chosen delegated_puzzle. Useful for collapsing many per-coin signatures into a single signature on the controller (for example a P2Eip712MessageLayer coin).

Fields

controller_puzzle_hash: Bytes32

Implementations

impl P2ControllerPuzzleLayer

pub fn new(controller_puzzle_hash: Bytes32) -> Self

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

Spend a coin locked by this layer with a delegated_spend previously authorised by the controller coin.

Trait Implementations

impl Clone for P2ControllerPuzzleLayer

fn clone(&self) -> P2ControllerPuzzleLayer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for P2ControllerPuzzleLayer

impl Debug for P2ControllerPuzzleLayer

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

Formats the value using the given formatter.

impl Eq for P2ControllerPuzzleLayer

impl Layer for P2ControllerPuzzleLayer

type Solution = P2ControllerPuzzleSolution<NodePtr, NodePtr>

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: &Allocator, solution: 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, ctx: &mut SpendContext, solution: 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 P2ControllerPuzzleLayer

fn eq(&self, other: &P2ControllerPuzzleLayer) -> bool

Equality operator ==.

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

Inequality operator !=.
