Struct NftOwnershipLayer

pub struct NftOwnershipLayer<T, I> {
    pub current_owner: Option<Bytes32>,
    pub transfer_layer: T,
    pub inner_puzzle: I,
}

The NFT ownership Layer keeps track of the current DID that owns the NFT. It also contains a transfer layer, which is used to transfer ownership of the NFT. The inner puzzle layer is commonly used for determining ownership (in the key sense, not DID).

Fields

current_owner: Option<Bytes32>

The DID owner of this NFT, if it’s currently assigned to one.

transfer_layer: T

The transfer layer, which is used to transfer ownership of the NFT.

inner_puzzle: I

The inner puzzle layer, commonly used for determining ownership.

Implementations

impl<T, I> NftOwnershipLayer<T, I>

pub fn new( current_owner: Option<Bytes32>, transfer_layer: T, inner_puzzle: I, ) -> Self

Trait Implementations

impl<T: Clone, I: Clone> Clone for NftOwnershipLayer<T, I>

fn clone(&self) -> NftOwnershipLayer<T, I>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug, I: Debug> Debug for NftOwnershipLayer<T, I>

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

Formats the value using the given formatter.

impl<T, I> Layer for NftOwnershipLayer<T, I>

where T: Layer, I: Layer,

type Solution = NftOwnershipLayerSolution<<I as Layer>::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: &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<T: PartialEq, I: PartialEq> PartialEq for NftOwnershipLayer<T, I>

fn eq(&self, other: &NftOwnershipLayer<T, I>) -> 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.

where T: ToTreeHash, I: ToTreeHash,

fn tree_hash(&self) -> TreeHash
