Struct EntityOpeningBalance 

pub struct EntityOpeningBalance {
    pub account_code: String,
    pub account_type: AccountType,
    pub debit: Decimal,
    pub credit: Decimal,
}

v5.3 — One per-account opening-balance record carried across periods. Produced by the prior period’s closing trial balance projection (group-side helper) and consumed by the orchestrator’s opening-balance phase to seed period-N+1 from period-N’s closing instead of generating a fresh opening.

debit and credit are both non-negative; at most one is non-zero (matches the underlying TrialBalanceLine invariant).

This carrier lives in datasynth-core so both datasynth-runtime (consumer via ShardContext) and datasynth-group (producer via extract_opening_balances) can reference it without a dependency cycle.

Fields

account_code: String

GL account code (e.g. "1100" for AR control).

account_type: AccountType

Account type — informational; the consumer applies its own sign convention based on it (assets/expenses → debit-positive, liabilities/equity/revenue → credit-positive).

debit: Decimal

Debit-side closing amount from the prior period (always non-negative; zero when the line was credit-balanced).

credit: Decimal

Credit-side closing amount from the prior period (always non-negative; zero when the line was debit-balanced).

Implementations

impl EntityOpeningBalance

pub fn net_balance(&self) -> Decimal

Net signed amount per the account’s normal balance side. Positive for accounts where the larger side matches the normal side; matches the convention GeneratedOpeningBalance.balances uses for its closing_balance map.

For Asset / ContraLiability / ContraEquity / Expense (debit- normal): returns debit - credit. For Liability / Equity / ContraAsset / Revenue (credit-normal): returns credit - debit.

Trait Implementations

impl Clone for EntityOpeningBalance

fn clone(&self) -> EntityOpeningBalance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityOpeningBalance

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EntityOpeningBalance

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EntityOpeningBalance

fn eq(&self, other: &EntityOpeningBalance) -> 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 EntityOpeningBalance

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
