TransactionContext

Struct TransactionContext 

Source
pub struct TransactionContext { /* private fields */ }
Available on crate feature postgres only.
Expand description

Active transaction context with repository access.

This struct holds the database transaction and provides access to entity repositories via extension traits generated by the macro.

§Automatic Rollback

If dropped without explicit commit, the transaction is automatically rolled back via the underlying database transaction’s Drop impl.

§Accessing Repositories

Each entity with #[entity(transactions)] generates an extension trait that adds an accessor method:

// For entity BankAccount, use:
ctx.bank_accounts().find_by_id(id).await?;
ctx.bank_accounts().create(dto).await?;
ctx.bank_accounts().update(id, dto).await?;

Implementations§

Source§

impl TransactionContext

Source

pub fn transaction(&mut self) -> &mut Transaction<'static, Postgres>

Get mutable reference to the underlying transaction.

Use this for custom queries within the transaction or for repository adapters to execute queries.

Source

pub async fn commit(self) -> Result<(), Error>

Commit the transaction.

Consumes self and commits all changes.

Source

pub async fn rollback(self) -> Result<(), Error>

Rollback the transaction.

Consumes self and rolls back all changes.
