//! # cala-ledger
//!
//! This crate provides a set of primitives for implementing an SQL-compatible
//! double-entry accounting system. This system is engineered specifically is
//! for dealing with money and building financial products.
//!
//! Visit the [website of the Cala project](https://cala.sh) for more info and
//! tutorials.
//!
//! ## Quick Start
//!
//! Here is how to initialize a ledger create a primitive template and post a transaction.
//! This is a toy example that brings all pieces together end-to-end.
//! Not recommended for real use.
//! ```rust
//! use cala_ledger::{account::*, journal::*, tx_template::*, *};
//! use rust_decimal::Decimal;
//! use uuid::uuid;
//!
//! async fn init_cala(journal_id: JournalId) -> anyhow::Result<CalaLedger, anyhow::Error> {
//! let cala_config = CalaLedgerConfig::builder()
//! .pg_con("postgres://user:password@localhost:5432/pg")
//! // .exec_migrations(true) # commented out for execution in CI
//! .build()?;
//! let cala = CalaLedger::init(cala_config).await?;
//!
//! // Initialize the journal - all entities are constructed via builders
//! let new_journal = NewJournal::builder()
//! .id(journal_id)
//! .name("Ledger")
//! .build()
//! .expect("Couldn't build NewJournal");
//! let _ = cala.journals().create(new_journal).await;
//!
//! // Initialize an income omnibus account
//! let main_account_id = uuid!("00000000-0000-0000-0000-000000000001");
//! let new_account = NewAccount::builder()
//! .id(main_account_id)
//! .name("Income")
//! .code("Income")
//! .build()?;
//! cala.accounts().create(new_account).await?;
//!
//! // Create the trivial 'income' template
//! let params = vec![
//! NewParamDefinition::builder()
//! .name("sender_account_id")
//! .r#type(ParamDataType::Uuid)
//! .build()?,
//! NewParamDefinition::builder()
//! .name("units")
//! .r#type(ParamDataType::Decimal)
//! .build()?,
//! ];
//!
//! let entries = vec![
//! NewTxTemplateEntry::builder()
//! .entry_type("'INCOME_DR'")
//! .account_id("params.sender_account_id")
//! .layer("SETTLED")
//! .direction("DEBIT")
//! .units("params.units")
//! .currency("'BTC'")
//! .build()?,

//! let tx_code = "GENERAL_INCOME";
//! let new_template = NewTxTemplate::builder()
//! .id(uuid::Uuid::now_v7())
//! .code(tx_code)
//! .params(params)
//! .transaction(
//! NewTxTemplateTransaction::builder()
//! .effective("date()")
//! .journal_id(format!("uuid('{}')", journal_id))
//! .build()?,
//! )
//! .entries(entries)
//! .build()?;
//!
//! cala.tx_templates().create(new_template).await?;
//! Ok(cala)
//! }
//!
//! #[tokio::main]
//! async fn main() -> anyhow::Result<()> {
//! let journal_id = JournalId::from(uuid!("00000000-0000-0000-0000-000000000001"));
//! let cala = init_cala(journal_id).await?;
//! // The account that is sending to the general income account
//! let sender_account_id = AccountId::new();
//! let sender_account = NewAccount::builder()
//! .id(sender_account_id)
//! .name(format!("Sender-{}", sender_account_id))
//! .code(format!("Sender-{}", sender_account_id))
//! .build()?;
//! cala.accounts().create(sender_account).await?;
//! // Prepare the input parameters that the template requires
//! let mut params = Params::new();
//! params.insert("sender_account_id", sender_account_id);
//! params.insert("units", Decimal::ONE);
//! // Create the transaction via the template
//! cala.post_transaction(TransactionId::new(), "GENERAL_INCOME", params)
//! .await?;
//!
//! let account_balance = cala
//! .balances()
//! .find(journal_id, sender_account_id, "BTC".parse()?)
//! .await?;
//!
//! let expected_balance = Decimal::new(-1, 0); // Define the expected balance
//! assert_eq!(account_balance.settled(), expected_balance);
//! Ok(())
//! }
