Struct Launcher 

Source 
pub struct Launcher { /* private fields */ }
Expand description

A singleton launcher is a coin that is spent within the same block to create a singleton. The first coin that is created is known as an “eve” singleton. The Launcher type allows you to get the launcher id before committing to creating the singleton.

Implementations§

impl Launcher

Source

pub fn create_eve_did( self, ctx: &mut SpendContext, p2_puzzle_hash: Bytes32, recovery_list_hash: Option<Bytes32>, num_verifications_required: u64, metadata: HashedPtr, ) -> Result<(Conditions, Did), DriverError>

Source

pub fn create_did<I>( self, ctx: &mut SpendContext, recovery_list_hash: Option<Bytes32>, num_verifications_required: u64, metadata: HashedPtr, inner: &I, ) -> Result<(Conditions, Did), DriverError>

impl Launcher

Source

pub fn from_coin(coin: Coin, conditions: Conditions) -> Self

Creates a new Launcher with the specified launcher coin and parent spend conditions.

Source

pub fn new(parent_coin_id: Bytes32, amount: u64) -> Self

The parent coin specified when constructing the Launcher will create the launcher coin. By default, no hint is used when creating the launcher coin. To specify a hint, use Launcher::with_memos.

Source

pub fn with_memos( parent_coin_id: Bytes32, amount: u64, memos: Memos<NodePtr>, ) -> Self

The parent coin specified when constructing the Launcher will create the launcher coin. The created launcher coin will be hinted to make identifying it easier later.

Source

pub fn create_early( parent_coin_id: Bytes32, amount: u64, ) -> (CreateCoin<NodePtr>, Self)

The parent coin specified when constructing the Launcher will create the launcher coin. By default, no hint is used when creating the coin. To specify a hint, use Launcher::create_early_with_memos.

This method is used to create the launcher coin immediately from the parent, then spend it later attached to any coin spend. For example, this is useful for minting NFTs from intermediate coins created with an earlier instance of a DID.

Source

pub fn create_early_with_memos( parent_coin_id: Bytes32, amount: u64, memos: Memos<NodePtr>, ) -> (CreateCoin<NodePtr>, Self)

The parent coin specified when constructing the Launcher will create the launcher coin. The created launcher coin will be hinted to make identifying it easier later.

This method is used to create the launcher coin immediately from the parent, then spend it later attached to any coin spend. For example, this is useful for minting NFTs from intermediate coins created with an earlier instance of a DID.

Source

pub fn with_singleton_amount(self, singleton_amount: u64) -> Self

Changes the singleton amount to differ from the launcher amount. This is useful in situations where the launcher amount is 0 and the singleton amount is 1, for example.

Source

pub fn singleton_amount(&self) -> u64

Returns the current singleton amount.

Source

pub fn coin(&self) -> Coin

The singleton launcher coin that will be created when the parent is spent.

Source

pub fn spend<T>( self, ctx: &mut SpendContext, singleton_inner_puzzle_hash: Bytes32, key_value_list: T, ) -> Result<(Conditions, Coin), DriverError>
where T: ToClvm<Allocator>,

Spends the launcher coin to create the eve singleton. Includes an optional metadata value that is traditionally a list of key value pairs.
