Struct PoolConnection 

pub struct PoolConnection { /* private fields */ }

A connection borrowed from the pool.

Uses std::sync::Mutex for interior mutability because the driver’s PoolGuard requires &mut self for queries, but the Executor trait takes &self. The mutex is uncontended in practice — a single connection is used by one caller at a time, never shared between concurrent callers.

Returned to the pool when dropped.

Trait Implementations

impl Debug for PoolConnection

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

impl Executor for PoolConnection

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

Execute a query and return all rows.

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

Execute a read-only query. May route to replicas in the future.

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