Crate nextsql_tokio_postgres_adapter 

tokio-postgres / deadpool-postgres adapter for NextSQL runtime.

Provides PooledPgClient which wraps a deadpool_postgres::Object and implements the NextSQL Client trait.

Also re-exports the core tokio-postgres types from the runtime crate for convenience.

Structs

PgClient

A wrapper around tokio_postgres::Client implementing the NextSQL Client trait.

PgRow

PgTransaction

A wrapper around tokio_postgres::Transaction implementing the NextSQL Transaction trait. Supports nested transactions (savepoints) and commit/rollback. Drop without calling commit() will rollback the transaction.

PooledPgClient

A wrapper around deadpool_postgres::Object implementing the NextSQL Client trait.

Enums

OwnedParam

An owned SQL parameter value. Used internally to convert borrowed &dyn ToSqlParam into owned values that can be moved into async futures.

Traits

Client

Trait for executing SQL queries against a database. Uses impl Future instead of async_trait to avoid proc macro compile overhead.

Row

Trait for reading typed values from a database result row.

ToSqlParam

Trait for values that can be bound as SQL query parameters.

Transaction

Trait for a database transaction. Supports the same query/execute operations as Client, plus commit/rollback. Dropping without calling commit() should rollback the transaction.

Functions

convert_params

Convert a slice of borrowed params to a vec of owned params.

owned_params_to_refs

Convert a slice of OwnedParam to a vec of trait-object references suitable for passing to tokio_postgres query methods.

to_owned_param

Convert a &dyn ToSqlParam to an owned parameter value by downcasting.
