Struct chain_impl_mockchain::transaction::builder::TxBuilderState

pub struct TxBuilderState<T> {
    data: Vec<u8>,
    tstruct: TransactionStruct,
    phantom: PhantomData<T>,
}

A Transaction builder with an associated state machine

Fields

data: Vec<u8>

tstruct: TransactionStruct

phantom: PhantomData<T>

Implementations

impl TxBuilderState<SetPayload>

pub fn new() -> Self

Create a new Tx builder

impl<State> TxBuilderState<State>

fn current_pos(&self) -> usize

impl TxBuilderState<SetPayload>

pub fn set_payload<P: Payload>(self, payload: &P) -> TxBuilderState<SetTtl<P>>

Set the payload of this transaction

pub fn set_nopayload(self) -> TxBuilderState<SetTtl<NoExtra>>

impl<P> TxBuilderState<SetTtl<P>>

pub fn set_expiry_date( self, valid_until: BlockDate ) -> TxBuilderState<SetIOs<P>>

impl<P> TxBuilderState<SetIOs<P>>

pub fn set_ios( self, inputs: &[Input], outputs: &[Output<Address>] ) -> TxBuilderState<SetWitnesses<P>>

Set the inputs and outputs of this transaction

This cannot accept more than 255 inputs, 255 outputs, since the length is encoded as u8, and hence will assert.

Note that further restriction apply to the ledger, which only accept up to 254 outputs

impl<P> TxBuilderState<SetWitnesses<P>>

pub fn get_auth_data_for_witness(&self) -> TransactionAuthData<'_>

Get the authenticated data consisting of the payload and the input/outputs

pub fn set_witnesses( self, witnesses: &[Witness] ) -> TxBuilderState<SetAuthData<P>>where P: Payload,

Set the witnesses of the transaction. There’s need to be 1 witness per inputs, although it is not enforced by this construction

Note that the same number of witnesses as the number of inputs need to be added here, otherwise an assert will raise.

pub fn set_witnesses_unchecked( self, witnesses: &[Witness] ) -> TxBuilderState<SetAuthData<P>>where P: Payload,

Set the witnesses of the transaction.

impl<P: Payload> TxBuilderState<SetAuthData<P>>

pub fn get_auth_data(&self) -> TransactionBindingAuthData<'_>

Get the authenticated data related to possible overall data for transaction and payload binding

pub fn set_payload_auth(self, auth_data: &P::Auth) -> Transaction<P>

Set the authenticated data

Trait Implementations

impl<T> Clone for TxBuilderState<T>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
