Struct trezor_client::SignTxProgress

pub struct SignTxProgress<'a> { /* private fields */ }

Object to track the progress in the transaction signing flow. The device will ask for various parts of the transaction and dependent transactions and can at any point also ask for user interaction. The information asked for by the device is provided based on a PSBT object and the resulting extra signatures are also added to the PSBT file.

It’s important to always first check with the finished() method if more data is requested by the device. If you’re not yet finished you must call the ack_psbt() method to send more information to the device.

Implementations

impl<'a> SignTxProgress<'a>

pub fn new(client: &mut Trezor, req: TxRequest) -> SignTxProgress<'_>

Only intended for internal usage.

pub fn tx_request(&self) -> &TxRequest

Inspector to the request message received from the device.

pub fn finished(&self) -> bool

Check whether or not the signing process is finished.

pub fn has_signature(&self) -> bool

Check if a signature is provided by the device.

pub fn get_signature(&self) -> Option<(usize, &[u8])>

Get the signature provided from the device along with the input index of the signature.

pub fn has_serialized_tx_part(&self) -> bool

Check if a part of the serialized signed tx is provided by the device.

pub fn get_serialized_tx_part(&self) -> Option<&[u8]>

Get the part of the serialized signed tx from the device.

pub fn ack_msg(
    self,
    ack: TxAck
) -> Result<TrezorResponse<'a, SignTxProgress<'a>, TxRequest>>

Manually provide a TxAck message to the device.

This method will panic if finished() returned true, so it should always be checked in advance.

pub fn ack_psbt(
    self,
    psbt: &PartiallySignedTransaction,
    network: Network
) -> Result<TrezorResponse<'a, SignTxProgress<'a>, TxRequest>>

Provide additional PSBT information to the device.

This method will panic if apply() returned true, so it should always be checked in advance.
