Struct tikv::storage::mvcc::reader::scanner::forward::Cursors[−][src]

pub struct Cursors<S: Snapshot> {
    lock: Cursor<S::Iter>,
    write: Cursor<S::Iter>,
    default: Option<Cursor<S::Iter>>,
}

Fields

lock: Cursor<S::Iter>write: Cursor<S::Iter>default: Option<Cursor<S::Iter>>

default cursor is lazy created only when it’s needed.

Implementations

`impl<S: Snapshot> Cursors<S>`[src]

`fn move_write_cursor_to_next_user_key( &mut self, current_user_key: &Key, statistics: &mut Statistics ) -> Result<()>`[src]

`fn ensure_default_cursor(&mut self, cfg: &mut ScannerConfig<S>) -> Result<()>`[src]

Create the default cursor if it doesn’t exist.
