Enum pallas_traverse::MultiEraTx

#[non_exhaustive]
pub enum MultiEraTx<'b> {
    AlonzoCompatible(Box<Cow<'b, MintedTx<'b>>>, Era),

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Byron(Box<Cow<'b, MintedTxPayload<'b>>>)

Implementations

impl<'b> MultiEraTx<'b>

pub fn from_byron(tx: &'b MintedTxPayload<'b>) -> Self

pub fn from_alonzo_compatible(tx: &'b MintedTx<'b>, era: Era) -> Self

pub fn from_babbage(tx: &'b MintedTx<'b>) -> Self

pub fn encode(&self) -> Vec<u8>

pub fn decode(era: Era, cbor: &'b [u8]) -> Result<Self, Error>

pub fn era(&self) -> Era

pub fn hash(&self) -> Hash<32>

pub fn outputs(&self) -> Vec<MultiEraOutput<'_>>

pub fn output_at(&self, index: usize) -> Option<MultiEraOutput<'_>>

pub fn inputs(&self) -> Vec<MultiEraInput<'_>>

pub fn reference_inputs(&self) -> Vec<MultiEraInput<'_>>

pub fn certs(&self) -> Vec<MultiEraCert<'_>>

pub fn mint(&self) -> MultiEraMint<'_>

pub fn collateral(&self) -> Vec<MultiEraInput<'_>>

pub fn collateral_return(&self) -> Option<MultiEraOutput<'_>>

pub fn consumes(&self) -> Vec<MultiEraInput<'_>>

Returns the list of inputs consumed by the Tx

Helper method to abstract the logic of which inputs are consumed depending on the validity of the Tx. If the Tx is valid, this method will return the list of inputs. If the tx is invalid, it will return the collateral.

pub fn produces(&self) -> Vec<(usize, MultiEraOutput<'_>)>

Returns a list of tuples of the outputs produced by the Tx with their indexes

Helper method to abstract the logic of which outputs are produced depending on the validity of the Tx. If the Tx is valid, this method will return the list of outputs. If the Tx is invalid it will return the collateral return if one is present or an empty list if not. Note that the collateral return output index is defined as the next available index after the txouts (Babbage spec, ch 4).

pub fn produces_at(&self, index: usize) -> Option<MultiEraOutput<'_>>

Returns the produced output at the given index if one exists

If the transaction is valid the outputs are produced, otherwise the collateral return output is produced at index |outputs.len()| if one is present. This function gets the produced output for an index if one exists. It behaves exactly as outputs_at for valid transactions, but for invalid transactions it returns None except for if the index points to the collateral-return output and one is present in the transaction, in which case it returns the collateral-return output.

pub fn requires(&self) -> Vec<MultiEraInput<'_>>

Returns the list of UTxO required by the Tx

Helper method to yield all of the UTxO that the Tx requires in order to be fulfilled. This includes normal inputs, reference inputs and collateral.

pub fn withdrawals(&self) -> MultiEraWithdrawals<'_>

pub fn fee(&self) -> Option<u64>

pub fn metadata(&self) -> MultiEraMeta<'_>
