Struct VecStore 

pub struct VecStore { /* private fields */ }

In-memory growable byte store (same Store contract as FileStore).

Implementations

impl VecStore

pub fn new() -> Self

pub fn into_inner(self) -> Vec<u8>

pub fn from_vec(buf: Vec<u8>) -> Self

pub fn as_slice(&self) -> &[u8]

Full buffer (read-only image of the logical file).

Trait Implementations

impl Debug for VecStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for VecStore

fn default() -> VecStore

Returns the “default value” for a type.

impl Store for VecStore

fn len(&self) -> Result<u64, DbError>

fn read_exact_at(&mut self, offset: u64, buf: &mut [u8]) -> Result<(), DbError>

fn write_all_at(&mut self, offset: u64, data: &[u8]) -> Result<(), DbError>

fn sync(&mut self) -> Result<(), DbError>

fn truncate(&mut self, len: u64) -> Result<(), DbError>

Shrink or grow the logical file to len bytes (used for crash recovery truncation).

fn is_empty(&self) -> Result<bool, DbError>
