SigHasher

zebra_chain::transaction::sighash

Struct SigHasher 

Source 
pub struct SigHasher {
    precomputed_tx_data: PrecomputedTxData,
}
Expand description

A SigHasher context which stores precomputed data that is reused between sighash computations for the same transaction.

Fields§

§precomputed_tx_data: PrecomputedTxData

Implementations§

Source§

impl SigHasher

Source

pub fn new( trans: &Transaction, nu: NetworkUpgrade, all_previous_outputs: Arc<Vec<Output>>, ) -> Result<Self, Error>

Create a new SigHasher for the given transaction.

§Panics
  • If trans can’t be converted to its librustzcash equivalent. This could happen, for example, if trans contains the nConsensusBranchId field, and nu doesn’t match it. More details in PrecomputedTxData::new.
  • If nu doesn’t contain a consensus branch id convertible to its librustzcash equivalent.
Source

pub fn sighash( &self, hash_type: HashType, input_index_script_code: Option<(usize, Vec<u8>)>, ) -> SigHash

Calculate the sighash for the current transaction.

§Details

The input_index_script_code tuple indicates the index of the transparent Input for which we are producing a sighash and the respective script code being validated, or None if it’s a shielded input.

§Panics
  • if the input index is out of bounds for self.inputs()
Source

pub fn orchard_bundle(&self) -> Option<Bundle<Authorized, ZatBalance>>

Returns the Orchard bundle in the precomputed transaction data.

Source

pub fn sapling_bundle(&self) -> Option<Bundle<Authorized, ZatBalance>>

Returns the Sapling bundle in the precomputed transaction data.
