Struct schemer_rusqlite::RusqliteAdapter

pub struct RusqliteAdapter<'a, E> { /* private fields */ }

Adapter between schemer and SQLite.

Implementations

impl<'a, E> RusqliteAdapter<'a, E>

pub fn new( conn: &'a mut Connection, table_name: Option<String> ) -> RusqliteAdapter<'a, E>

Construct a SQLite 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 = rusqlite::Connection::open_in_memory().unwrap();
let adapter: schemer_rusqlite::RusqliteAdapter<RusqliteError> = schemer_rusqlite::RusqliteAdapter::new(&mut conn, None);

pub fn init(&self) -> Result<(), RusqliteError>

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

type Error = E

Type of errors returned by this adapter.

fn apply_migration( &mut self, migration: &Self::MigrationType ) -> Result<(), Self::Error>
