Implementations

impl LazyContainer

pub fn init(path: impl AsRef<Path>) -> Result<Self, Error>

Initialises a new, empty LazyContainer at the specified path.

pub fn load(path: impl AsRef<Path>) -> Result<Self, LDBError>

Loads a pre-existing LazyContainer directory at a specified path.

Will throw an error if the directory doesn’t exist or there is an io::Error.

pub fn data_writer( &self, key: impl AsRef<Path>, ) -> Result<FileWrapper, LDBError>

Generates a FileWrapper in write mode from a key (like a relative file path)

If the data already exists, it will try to remove it

pub fn new_container( &self, key: impl AsRef<Path>, ) -> Result<LazyContainer, LDBError>

Generates a nested LazyContainer within this container

If container already exists it will wipe and replace it.

pub fn child_container( &self, key: impl AsRef<Path>, ) -> Result<LazyContainer, LDBError>

Gets a nested LazyContainer within this container

If container already exists it will load it Otherwise it will initialise a new one

pub fn read_data(&self, key: impl AsRef<Path>) -> Result<LazyData, LDBError>

Reads nested LazyData within this container

pub fn read_container( &self, key: impl AsRef<Path>, ) -> Result<LazyContainer, LDBError>

Reads nexted LazyContainer within this container

pub fn remove(&self, key: impl AsRef<Path>) -> Result<(), Error>

Tries to remove item at specified key; returns result

pub fn wipe(&self) -> Result<(), Error>

Tries to wipe container’s contents; returns result

pub fn path(&self) -> &Path

Returns a reference to the container’s path
