Struct rustdb::stg::MemFile

pub struct MemFile { /* private fields */ }

Simple implementation of Storage using Vec<u8>.

Implementations

impl MemFile

pub fn new() -> Box<Self>

Get a new (boxed) MemFile.

Trait Implementations

impl Default for MemFile

fn default() -> MemFile

Returns the “default value” for a type.

impl Storage for MemFile

fn size(&self) -> u64

Get the size of the underlying storage. Note : this is valid initially and after a commit but is not defined after write is called.

fn read(&self, off: u64, bytes: &mut [u8])

Read data from storage.

fn write(&self, off: u64, bytes: &[u8])

Write byte slice to storage.

fn commit(&self, size: u64)

Finish write transaction, size is new size of underlying storage.

fn write_vec(&self, start: u64, data: Vec<u8>)

Write byte Vec to storage.

fn write_data(&self, start: u64, data: Data, off: usize, len: usize)

Write Data slice to storage.

fn write_u64(&self, start: u64, value: u64)

Write u64 to storage.

fn read_u64(&self, start: u64) -> u64

Read u64 from storage.
