Implementations

impl<C> MemVfsUtil<C>

where C: OsCallback,

pub fn new() -> MemVfsUtil<C>

Get management tool

impl<C> MemVfsUtil<C>

where C: OsCallback,

pub fn import_db(&self, filename: &str, bytes: &[u8]) -> Result<(), MemVfsError>

Import the database.

If the database is imported with WAL mode enabled, it will be forced to write back to legacy mode, see https://sqlite.org/forum/forumpost/67882c5b04

If the imported database is encrypted, use import_db_unchecked instead.

pub fn import_db_unchecked( &self, filename: &str, bytes: &[u8], page_size: usize, ) -> Result<(), MemVfsError>

import_db without checking, can be used to import encrypted database.

pub fn export_db(&self, filename: &str) -> Result<Vec<u8>, MemVfsError>

Export the database.

pub fn delete_db(&self, filename: &str)

Delete the specified database, make sure that the database is closed.

pub fn clear_all(&self)

Delete all database, make sure that all database is closed.

pub fn exists(&self, filename: &str) -> bool

Does the database exists.

pub fn list(&self) -> Vec<String>

List all files.

pub fn count(&self) -> usize
