Struct CardanoTransactionsSigningConfig 

pub struct CardanoTransactionsSigningConfig {
    pub security_parameter: BlockNumber,
    pub step: BlockNumber,
}

Configuration for the signing of Cardano transactions

Allow to compute the block number to be signed based on the chain tip block number.

Fields

security_parameter: BlockNumber

Number of blocks to discard from the tip of the chain when importing transactions.

step: BlockNumber

The number of blocks between signature of the transactions.

Note: The step is adjusted to be a multiple of the block range length in order to guarantee that the block number signed in a certificate is effectively signed.

Implementations

impl CardanoTransactionsSigningConfig

pub fn compute_block_number_to_be_signed( &self, block_number: BlockNumber, ) -> BlockNumber

Compute the block number to be signed based on the chain tip block number.

The latest block number to be signed is the highest multiple of the step less or equal than the block number minus the security parameter.

The formula is as follows:

block_number = ⌊(tip.block_number - security_parameter) / step⌋ × step - 1

where ⌊x⌋ is the floor function which rounds to the greatest integer less than or equal to x.

Notes:

• The step is adjusted to be a multiple of the block range length in order to guarantee that the block number signed in a certificate is effectively signed.
• 1 is subtracted to the result because block range end is exclusive (ie: a BlockRange over 30..45 finish at 44 included, 45 is included in the next block range).

Trait Implementations

impl Clone for CardanoTransactionsSigningConfig

fn clone(&self) -> CardanoTransactionsSigningConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CardanoTransactionsSigningConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CardanoTransactionsSigningConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Dummy for CardanoTransactionsSigningConfig

fn dummy() -> Self

Return a dummy CardanoTransactionsSigningConfig (test-only).

impl PartialEq for CardanoTransactionsSigningConfig

fn eq(&self, other: &CardanoTransactionsSigningConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for CardanoTransactionsSigningConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
