Implementations

impl FileWrapper

pub fn new_reader(file: File) -> Self

Constructs a new FileWrapper::Reader varient

pub fn new_writer(file: File) -> Self

Constructs a new FileWrapper::Writer varient

pub fn write(&mut self, byte: &[u8]) -> Result<(), LDBError>

Writes a byte slice into the file

pub fn read(&mut self, length: usize) -> Result<Box<[u8]>, LDBError>

Reads a set amount of bytes from a file by padding out undefined portions with 0u8

pub fn read_opt(&mut self, length: usize) -> Result<Option<Box<[u8]>>, LDBError>

pub fn finish(self) -> Result<(), Error>

Deconstruct the wrapper properly with all of the buffers and such

pub fn read_to_end(self) -> Result<Box<[u8]>, LDBError>

Reads to the end of the file (consumes wrapper)
