Crate persistant_sqlx 

PersistAnt’s relational driver over sqlx (PostgreSQL first).

PgBackend implements persistant_relational::RelationalBackend. The concrete sqlx::PgPool is available through PgBackend::pool, so a program that wants compile-time-checked sqlx::query! keeps it (D1, C+): this crate does not hide sqlx.

Failures are classified from the server’s SQLSTATE into persistant_relational::RelError.

Structs

ConnectOptions

Settings for PgBackend::connect_with (and MysqlBackend::connect_with, feature mysql).

MigrateReport

What a successful run did.

Migration

One migration: a version, a description and the SQL text. The text is hashed; changing a migration that has been applied is an error, never a silent re-run.

PgBackend

A PostgreSQL database behind an sqlx pool.

PgTx

A PostgreSQL transaction.

Enums

FromSqlxError

Why an sqlx Migrator cannot be run by Migrates::migrate as it stands.

MigrateError

Why a migration run stopped.

TlsPolicy

How a connection is secured. A typed setting, not a sslmode= string someone has to remember.

Traits

Migrates

A relational backend that keeps a migration ledger.

Functions

migrations_from_sqlx

The migrations of an sqlx Migrator (sqlx::migrate!("./migrations") or Migrator::new(path)) as Migrations for Migrates::migrate, in the order sqlx would run them.
