pub struct PageFile {
    pub num_pages: u32,
    pub version: u32,

}

Implementations

impl PageFile

pub fn create(path: &Path) -> Result<Self, MqdbError>

pub fn open(path: &Path) -> Result<Self, MqdbError>

pub fn read_page(&mut self, page_id: u32) -> Result<[u8; 8192], MqdbError>

pub fn write_page( &mut self, page_id: u32, data: &[u8; 8192], ) -> Result<(), MqdbError>

pub fn append_page(&mut self, data: &[u8; 8192]) -> Result<u32, MqdbError>

pub fn sync_header(&mut self) -> Result<(), MqdbError>

Persists num_pages if it changed since the last write. Must run before the file is reopened from disk (see Storage::flush_catalog).
