Control the Store and make changes to files

Required Methods

fn add_file(vfs: *mut sqlite3_vfs, file: &str, flags: i32)

Adding files to the Store, use for xOpen

fn contains_file(vfs: *mut sqlite3_vfs, file: &str) -> bool

Checks if the specified file exists in the Store, use for xOpen

fn delete_file(vfs: *mut sqlite3_vfs, file: &str) -> Option<S>

Delete the specified file in the Store, use for xClose and xDelete

fn with_file<F: Fn(&S) -> i32>(vfs_file: &SQLiteVfsFile, f: F) -> Option<i32>

Read the file contents, use for xRead, xFileSize

fn with_file_mut<F: Fn(&mut S) -> i32>( vfs_file: &SQLiteVfsFile, f: F, ) -> Option<i32>

Write the file contents, use for xWrite, xTruncate

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
