Struct SettlementLayer

pub struct SettlementLayer;

The settlement Layer is used to spend coins that are part of an offer.

Trait Implementations

impl Clone for SettlementLayer

fn clone(&self) -> SettlementLayer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SettlementLayer

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

Formats the value using the given formatter.

impl Layer for SettlementLayer

type Solution = SettlementPaymentsSolution

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 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 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_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 SettlementLayer

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