pub struct Manager { /* private fields */ }

Expand description

Manages database migration.

Implementations

source

impl Manager

source

pub fn new(config: Config) -> Self

Creates new migration manager with given configuration.

source

pub fn add_migration<T>(&mut self, migration: T) -> Result<()> where
T: Migration,

Adds new migration rules.

source

pub fn execute(&mut self, old_path: &Path, version: u32) -> Result<PathBuf>

Performs migration in order, starting with a source path, migrating between two temporary databases, and producing a path where the final migration lives.

source

pub fn is_needed(&self, version: u32) -> bool

Returns true if migration is needed.
