Struct Transaction 

pub struct Transaction { /* private fields */ }

A single transaction attempt, handed to the closure passed to crate::Client::transaction. Exposes the same query methods as crate::Client itself (minus analyze, which the Python client also never runs inside an explicit transaction).

Implementations

impl Transaction

pub async fn query<R: Queryable, A: QueryArgs + ?Sized>( &self, pyql: &str, args: &A, ) -> Result<Vec<R>>

pub async fn query_single<R: Queryable, A: QueryArgs + ?Sized>( &self, pyql: &str, args: &A, ) -> Result<Option<R>>

pub async fn query_required_single<R: Queryable, A: QueryArgs + ?Sized>( &self, pyql: &str, args: &A, ) -> Result<R>

pub async fn execute<A: QueryArgs + ?Sized>( &self, pyql: &str, args: &A, ) -> Result<()>

A write inside a transaction still evicts immediately: the cache is never populated from inside a transaction, so an aborted attempt can only over-evict — which costs a re-read and never serves stale data.

pub async fn query_json<A: QueryArgs + ?Sized>( &self, pyql: &str, args: &A, ) -> Result<String>

pub async fn query_single_json<A: QueryArgs + ?Sized>( &self, pyql: &str, args: &A, ) -> Result<Option<String>>

pub async fn query_required_single_json<A: QueryArgs + ?Sized>( &self, pyql: &str, args: &A, ) -> Result<String>
