Struct bitcoin_scripting::TaprootBuilder

pub struct TaprootBuilder { /* private fields */ }

| Utility class to construct Taproot | outputs from internal key and script | tree. |

Implementations

impl TaprootBuilder

pub fn is_valid(&self) -> bool

| Return true if so far all input was valid. |

pub fn is_complete(&self) -> bool

| Return whether there were either no | leaves, or the leaves form a Huffman | tree. |

impl TaprootBuilder

pub fn combine(&mut self, a: NodeInfo, b: NodeInfo) -> NodeInfo

| Combine information about a parent | Merkle tree node from its child nodes. |

pub fn insert(&mut self, node: NodeInfo, depth: i32)

| Insert information about a node at a | certain depth, and propagate information | up. |

pub fn valid_depths(&mut self, depths: &Vec<i32>) -> bool

| Check if a list of depths is legal (will | lead to IsComplete()). |

pub fn add( &mut self, depth: i32, script: &Script, leaf_version: i32, track: Option<bool> ) -> &mut TaprootBuilder

| Add a new script at a certain depth in | the tree. Add() operations must be called | in depth-first traversal order of binary | tree. If track is true, it will be included | in the GetSpendData() output. |

pub fn add_omitted(&mut self, depth: i32, hash: &u256) -> &mut TaprootBuilder

| Like Add(), but for a Merkle node with | a given hash to the tree. |

pub fn finalize(&mut self, internal_key: &XOnlyPubKey) -> &mut TaprootBuilder

| Finalize the construction. Can only | be called when IsComplete() is true. | internal_key.IsFullyValid() must | be true. |

pub fn get_output(&mut self) -> WitnessV1Taproot

| Compute scriptPubKey (after Finalize()). |

pub fn get_spend_data(&self) -> TaprootSpendData

| Compute spending data (after Finalize()). |
