Enum rexie::Direction

pub enum Direction {
    Next,
    NextUnique,
    Prev,
    PrevUnique,
}

Specifies the cursor direction.

Variants

Next

Next causes the cursor to be opened at the start of the source. When iterated, the cursor yields all records, including duplicates, in monotonically increasing order of keys.

NextUnique

NextUnique causes the cursor to be opened at the start of the source. When iterated, the cursor does not yield records with the same key, but otherwise yields all records, in monotonically increasing order of keys.

Prev

Prev causes the cursor to be opened at the end of the source. When iterated, the cursor yields all records, including duplicates, in monotonically decreasing order of keys.

PrevUnique

PrevUnique causes the cursor to be opened at the end of the source. When iterated, the cursor does not yield records with the same key, but otherwise yields all records, in monotonically decreasing order of keys.

Trait Implementations

impl Clone for CursorDirection

fn clone(&self) -> CursorDirection

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CursorDirection

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for CursorDirection

fn default() -> CursorDirection

Returns the “default value” for a type.

impl From<CursorDirection> for JsValue

fn from(direction: CursorDirection) -> JsValue

Converts to this type from the input type.

impl PartialEq for CursorDirection

fn eq(&self, other: &CursorDirection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<IdbCursorDirection> for CursorDirection

type Error = Error

The type returned in the event of a conversion error.

fn try_from( direction: IdbCursorDirection, ) -> Result<CursorDirection, <CursorDirection as TryFrom<IdbCursorDirection>>::Error>

Performs the conversion.

impl TryFrom<JsValue> for CursorDirection

type Error = Error

The type returned in the event of a conversion error.

fn try_from( value: JsValue, ) -> Result<CursorDirection, <CursorDirection as TryFrom<JsValue>>::Error>

Performs the conversion.
