Struct SqliteDatasetStorage 

pub struct SqliteDatasetStorage { /* private fields */ }

Available on crate features dataset and sqlite and std only.

The SqliteDatasetStorage struct represents a SQLite database for storing datasets. It consists of an optional name, a database file path, and a base directory for storage.

Implementations

impl SqliteDatasetStorage

pub fn from_name(name: &str) -> SqliteDatasetStorage

Creates a new instance of SqliteDatasetStorage using a dataset name.

Arguments

• name - A string slice that holds the name of the dataset.

pub fn from_file<P>(db_file: P) -> SqliteDatasetStorage

where P: AsRef<Path>,

Creates a new instance of SqliteDatasetStorage using a database file path.

Arguments

• db_file - A reference to the Path that represents the database file path.

pub fn with_base_dir<P>(self, base_dir: P) -> SqliteDatasetStorage

where P: AsRef<Path>,

Sets the base directory for storing the dataset.

Arguments

• base_dir - A string slice that represents the base directory.

pub fn exists(&self) -> bool

Checks if the database file exists in the given path.

Returns

• A boolean value indicating whether the file exists or not.

pub fn db_file(&self) -> PathBuf

Fetches the database file path.

Returns

• A PathBuf instance representing the file path.

pub fn base_dir(base_dir: Option<PathBuf>) -> PathBuf

Determines the base directory for storing the dataset.

Arguments

• base_dir - An Option that may contain a PathBuf instance representing the base directory.

Returns

• A PathBuf instance representing the base directory.

pub fn writer<I>( &self, overwrite: bool, ) -> Result<SqliteDatasetWriter<I>, SqliteDatasetError>

where I: Clone + Send + Sync + Serialize + DeserializeOwned,

Provides a writer instance for the SQLite dataset.

Arguments

• overwrite - A boolean indicating if the existing database file should be overwritten.

Returns

• A Result which is Ok if the writer could be created, Err otherwise.

pub fn reader<I>( &self, split: &str, ) -> Result<SqliteDataset<I>, SqliteDatasetError>

where I: Clone + Send + Sync + Serialize + DeserializeOwned,

Provides a reader instance for the SQLite dataset.

Arguments

• split - A string slice that defines the data split for reading (e.g., “train”, “test”).

Returns

• A Result which is Ok if the reader could be created, Err otherwise.
