source · [−]pub struct PostgresAdapter<'a> { /* private fields */ }
Expand description
Adapter between schemer and PostgreSQL.
Implementations
sourceimpl<'a> PostgresAdapter<'a>
impl<'a> PostgresAdapter<'a>
sourcepub fn new(
conn: &'a mut Client,
table_name: Option<String>
) -> PostgresAdapter<'a>
pub fn new(
conn: &'a mut Client,
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 mut conn = postgres::Client::connect(
"postgresql://postgres@localhost",
postgres::NoTls).unwrap();
let adapter = schemer_postgres::PostgresAdapter::new(&mut conn, None);
sourcepub fn init(&mut self) -> Result<(), PostgresError>
pub fn init(&mut 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.
