Enum QueryTarget 

pub enum QueryTarget<'a> {
    Pool(&'a Pool),
    Conn(&'a mut PoolConnection),
    Tx(&'a mut Transaction),
}

Concrete enum for query dispatch. Replaces the Executor trait.

Generated code converts the user-supplied executor (&Pool, &mut PoolConnection, or &mut Transaction) into QueryTarget via Into, then calls query_raw / query_raw_readonly / execute_raw.

Pool takes a shared reference (&Pool) because it acquires from the pool internally. PoolConnection and Transaction take exclusive references (&mut) — no Mutex needed.

Variants

Pool(&'a Pool)

Conn(&'a mut PoolConnection)

Tx(&'a mut Transaction)

Implementations

impl<'a> QueryTarget<'a>

pub fn query_raw( self, sql: &str, sql_hash: u64, params: &[&(dyn Encode + Sync)], ) -> BsqlResult<OwnedResult>

Execute a query and return all rows.

pub fn query_raw_readonly( self, sql: &str, sql_hash: u64, params: &[&(dyn Encode + Sync)], ) -> BsqlResult<OwnedResult>

Execute a read-only query. Routes to replicas for Pool when configured.

pub fn execute_raw( self, sql: &str, sql_hash: u64, params: &[&(dyn Encode + Sync)], ) -> BsqlResult<u64>

Execute a query and return the number of affected rows.
