BIP 371 Taproot fields for a single PSBT input.

Fields

tap_key_sig: Option<String>

Schnorr signature for key-path spending (PSBT_IN_TAP_KEY_SIG).

Must be 64 bytes (without sighash type) or 65 bytes (with sighash type).

tap_script_sigs: Vec<(String, String)>

Script-path Schnorr signatures: (control_block_hex, sig_hex) pairs (PSBT_IN_TAP_SCRIPT_SIG).

tap_leaf_scripts: Vec<TapLeafScript>

Tapscript leaves in the spend path (PSBT_IN_TAP_LEAF_SCRIPT).

tap_bip32_derivations: Vec<TapBip32Derivation>

BIP 32 derivation paths for Taproot keys (PSBT_IN_TAP_BIP32_DERIVATION).

tap_internal_key: Option<String>

x-only internal key (PSBT_IN_TAP_INTERNAL_KEY).

tap_merkle_root: Option<String>

Taproot Merkle root (PSBT_IN_TAP_MERKLE_ROOT).

None indicates a key-path-only output (no script tree).

Implementations

impl TaprootInputFields

pub fn new() -> Self

Construct an empty set of Taproot input fields.

pub fn with_key_sig(self, sig: String) -> Result<Self, TaprootPsbtError>

Attach a key-path Schnorr signature.

The signature must be exactly 64 bytes (without explicit sighash type) or 65 bytes (with an appended sighash type byte).

pub fn with_internal_key(self, key: String) -> Result<Self, TaprootPsbtError>

Attach the x-only internal key.

Must be exactly 32 bytes (64 hex chars).

pub fn with_merkle_root(self, root: String) -> Result<Self, TaprootPsbtError>

Attach the Taproot Merkle root.

Must be exactly 32 bytes (64 hex chars).

pub fn add_leaf_script(&mut self, leaf: TapLeafScript)

Append a Tapscript leaf.

pub fn add_bip32_derivation(&mut self, deriv: TapBip32Derivation)

Append a BIP 32 derivation record.

pub fn is_key_path_signed(&self) -> bool

Returns true when a key-path Schnorr signature is present.

pub fn is_script_path_signed(&self) -> bool

Returns true when at least one script-path signature is present.

pub fn is_finalized(&self) -> bool

Returns true when the input is finalised via either key-path or script-path signing.

pub fn validate(&self) -> Result<(), TaprootPsbtError>

Validate all Taproot fields.
