Struct grin_core::libtx::slate::Slate

pub struct Slate {
    pub num_participants: usize,
    pub id: Uuid,
    pub tx: Transaction,
    pub amount: u64,
    pub fee: u64,
    pub height: u64,
    pub lock_height: u64,
    pub participant_data: Vec<ParticipantData>,
}

A 'Slate' is passed around to all parties to build up all of the public transaction data needed to create a finalized transaction. Callers can pass the slate around by whatever means they choose, (but we can provide some binary or JSON serialization helpers here).

Fields

num_participants: usize

The number of participants intended to take part in this transaction

id: Uuid

Unique transaction ID, selected by sender

tx: Transaction

The core transaction data: inputs, outputs, kernels, kernel offset

amount: u64

base amount (excluding fee)

fee: u64

fee amount

height: u64

Block height for the transaction

lock_height: u64

Lock height

participant_data: Vec<ParticipantData>

Participant data, each participant in the transaction will insert their public data here. For now, 0 is sender and 1 is receiver, though this will change for multi-party

Methods

impl Slate

pub fn blank(num_participants: usize) -> Slate

Create a new slate

pub fn add_transaction_elements<K>(     &mut self,     keychain: &K,     elems: Vec<Box<Append<K>>> ) -> Result<BlindingFactor, Error> where     K: Keychain,

Adds selected inputs and outputs to the slate's transaction Returns blinding factor

pub fn fill_round_1<K>(     &mut self,     keychain: &K,     sec_key: &mut SecretKey,     sec_nonce: &SecretKey,     participant_id: usize,     message: Option<String> ) -> Result<(), Error> where     K: Keychain,

Completes callers part of round 1, adding public key info to the slate

pub fn fill_round_2<K>(     &mut self,     keychain: &K,     sec_key: &SecretKey,     sec_nonce: &SecretKey,     participant_id: usize ) -> Result<(), Error> where     K: Keychain,

Completes caller's part of round 2, completing signatures

pub fn finalize<K>(&mut self, keychain: &K) -> Result<(), Error> where     K: Keychain,

Creates the final signature, callable by either the sender or recipient (after phase 3: sender confirmation) TODO: Only callable by receiver at the moment

pub fn verify_messages(&self, secp: &Secp256k1) -> Result<(), Error>

Verifies any messages in the slate's participant data match their signatures
