Struct mithril_common::test_utils::CardanoTransactionsBuilder

pub struct CardanoTransactionsBuilder { /* private fields */ }

Builder to easily build transactions with consistent values.

Note: the names generated for the transaction hashes and block hashes are not meaningful.

Example ‘build_transactions’

    use mithril_common::entities::{BlockNumber, CardanoTransaction, SlotNumber};
    use mithril_common::test_utils::CardanoTransactionsBuilder;

    let txs = CardanoTransactionsBuilder::new()
        .max_transactions_per_block(3)
        .blocks_per_block_range(2)
        .build_transactions(8);

    assert_eq!(8, txs.len());
    assert_eq!(
        vec![
            CardanoTransaction::new("tx-hash-0-100", BlockNumber(0), SlotNumber(100), "block-hash-0"),
            CardanoTransaction::new("tx-hash-0-101", BlockNumber(0), SlotNumber(101), "block-hash-0"),
            CardanoTransaction::new("tx-hash-0-102", BlockNumber(0), SlotNumber(102), "block-hash-0"),
            CardanoTransaction::new("tx-hash-1-103", BlockNumber(1), SlotNumber(103), "block-hash-1"),
            CardanoTransaction::new("tx-hash-1-104", BlockNumber(1), SlotNumber(104), "block-hash-1"),
            CardanoTransaction::new("tx-hash-1-105", BlockNumber(1), SlotNumber(105), "block-hash-1"),
            CardanoTransaction::new("tx-hash-15-106", BlockNumber(15), SlotNumber(106), "block-hash-15"),
            CardanoTransaction::new("tx-hash-15-107", BlockNumber(15), SlotNumber(107), "block-hash-15")
        ],
        txs
    );

Example ‘build_block_ranges’

    use mithril_common::entities::{BlockNumber, CardanoTransaction, SlotNumber};
    use mithril_common::test_utils::CardanoTransactionsBuilder;

    let txs = CardanoTransactionsBuilder::new()
        .max_transactions_per_block(3)
        .blocks_per_block_range(2)
        .build_block_ranges(2);

    assert_eq!(3 * 2 * 2, txs.len());
    assert_eq!(
        vec![
            CardanoTransaction::new("tx-hash-0-100", BlockNumber(0), SlotNumber(100), "block-hash-0"),
            CardanoTransaction::new("tx-hash-0-101", BlockNumber(0), SlotNumber(101), "block-hash-0"),
            CardanoTransaction::new("tx-hash-0-102", BlockNumber(0), SlotNumber(102), "block-hash-0"),
            CardanoTransaction::new("tx-hash-1-103", BlockNumber(1), SlotNumber(103), "block-hash-1"),
            CardanoTransaction::new("tx-hash-1-104", BlockNumber(1), SlotNumber(104), "block-hash-1"),
            CardanoTransaction::new("tx-hash-1-105", BlockNumber(1), SlotNumber(105), "block-hash-1"),
            CardanoTransaction::new("tx-hash-15-106", BlockNumber(15), SlotNumber(106), "block-hash-15"),
            CardanoTransaction::new("tx-hash-15-107", BlockNumber(15), SlotNumber(107), "block-hash-15"),

            CardanoTransaction::new("tx-hash-16-110", BlockNumber(16), SlotNumber(110), "block-hash-16"),
            CardanoTransaction::new("tx-hash-16-111", BlockNumber(16), SlotNumber(111), "block-hash-16"),

Implementations

impl CardanoTransactionsBuilder

pub fn new() -> Self

CardanoTransactionsBuilder constructor.

pub fn max_transactions_per_block(self, transactions_per_block: usize) -> Self

Define how many transactions we generate in each block.

pub fn blocks_per_block_range(self, blocks_per_block_range: usize) -> Self

Define how many blocks we generate in each block_range. If we set too many blocks for a block_range, this function panic.

pub fn build_transactions( self, transactions_count: usize, ) -> Vec<CardanoTransaction>

Build the number of transactions requested.

pub fn build_block_ranges( self, block_ranges_count: usize, ) -> Vec<CardanoTransaction>

Build a list of transactions to get the number of block range requested.

Trait Implementations

impl Default for CardanoTransactionsBuilder

fn default() -> Self

Returns the “default value” for a type.
