Struct schemer_postgres::PostgresAdapter

pub struct PostgresAdapter<'a> { /* fields omitted */ }

Adapter between schemer and PostgreSQL.

Methods

impl<'a> PostgresAdapter<'a>

fn new(conn: &'a Connection, table_name: Option<String>) -> PostgresAdapter<'a>

Construct a PostgreSQL schemer adapter.

table_name specifies the name of the table that schemer will use for storing metadata about applied migrations. If None, a default will be used.

let conn = postgres::Connection::connect(
    "postgresql://postgres@localhost/?search_path=pg_temp",
    postgres::TlsMode::None).unwrap();
let adapter = schemer_postgres::PostgresAdapter::new(&conn, None);

fn init(&self) -> Result<(), PostgresError>

Initialize the schemer metadata schema. This must be called before using Migrator with this adapter. This is safe to call multiple times.
