Struct MemChunksFile 

pub struct MemChunksFile { /* private fields */ }

An in-memory file implementation that stores data in fixed-size chunks. Suitable for temporary files.

Implementations

impl MemChunksFile

pub fn new(chunk_size: usize) -> Self

Creates a new MemChunksFile with a specified chunk size.

pub fn waiting_for_write() -> Self

Creates a MemChunksFile where the chunk size is determined by the size of the first write operation.

This is often used for the main DB file implementation.

Trait Implementations

impl Default for MemChunksFile

fn default() -> Self

Returns the “default value” for a type.

impl VfsFile for MemChunksFile

fn read(&self, buf: &mut [u8], offset: usize) -> VfsResult<bool>

Abstraction of xRead, returns true for SQLITE_OK and false for SQLITE_IOERR_SHORT_READ

fn write(&mut self, buf: &[u8], offset: usize) -> VfsResult<()>

Abstraction of xWrite

fn truncate(&mut self, size: usize) -> VfsResult<()>

Abstraction of xTruncate

fn flush(&mut self) -> VfsResult<()>

Abstraction of xSync

fn size(&self) -> VfsResult<usize>

Abstraction of xFileSize
