Struct IndexedDBCursorSnapshot 

pub struct IndexedDBCursorSnapshot {
    pub index_cursor: bool,
    pub keys_only: bool,
    pub reverse: bool,
    pub unique: bool,
    pub entries: Vec<IndexedDBCursorSnapshotEntry>,
    pub pos: isize,
}

Provider-side IndexedDB cursor snapshot.

The snapshot sorts rows, applies IndexedDB range bounds, and implements movement semantics for native Rust providers without exposing wire message types.

Fields

index_cursor: bool

Whether entry keys contain secondary-index values.

keys_only: bool

Whether returned cursor entries should omit records.

reverse: bool

Whether entries are ordered from greatest to least key.

unique: bool

Whether duplicate index keys are collapsed while iterating.

entries: Vec<IndexedDBCursorSnapshotEntry>

Sorted and range-filtered entries used by cursor movement.

pos: isize

Current cursor position, or -1 when unpositioned.

Implementations

impl IndexedDBCursorSnapshot

pub fn new(req: &IndexedDBOpenCursorRequest) -> Self

Creates an empty provider-side cursor snapshot from a native request.

pub fn load( &mut self, entries: Vec<IndexedDBCursorSnapshotEntry>, range: Option<&KeyRange>, ) -> Result<(), IndexedDBError>

Sorts entries, applies the supplied key range, and stores the snapshot.

pub fn apply_range( &self, entries: Vec<IndexedDBCursorSnapshotEntry>, range: Option<&KeyRange>, ) -> Result<Vec<IndexedDBCursorSnapshotEntry>, IndexedDBError>

Returns entries that satisfy the supplied key range without mutating state.

pub fn next( &mut self, ) -> Result<Option<&IndexedDBCursorSnapshotEntry>, IndexedDBError>

Advances to the next entry, or returns None when exhausted.

pub fn continue_to_key( &mut self, target: &Value, ) -> Result<Option<&IndexedDBCursorSnapshotEntry>, IndexedDBError>

Advances to target or the next entry past it for this direction.

pub fn advance( &mut self, count: i32, ) -> Result<Option<&IndexedDBCursorSnapshotEntry>, IndexedDBError>

Skips count entries and returns the new current entry.

pub fn current(&self) -> Result<&IndexedDBCursorSnapshotEntry, IndexedDBError>

Returns the currently positioned entry.

Trait Implementations
