Enum fdb_rl::cursor::key_value_cursor::KeyValueContinuationInternal

pub(crate) enum KeyValueContinuationInternal {
    V1(KeyValueContinuationInternalV1),
}

Internal representation of key-value continuation.

We define this type so we can implement Continuation trait on it. In addition it has TryFrom<Bytes> for KeyValueContinuationInternal and TryFrom<KeyValueContinuationInternal> for Bytes traits implemented so we can convert between Bytes and KeyValueContinuationInternal.

V1(KeyValueContinuationInternalV1)

Implementations

impl KeyValueContinuationInternal

pub(crate) fn new_v1_begin_marker() -> KeyValueContinuationInternal

Create a V1 begin marker value.

pub(crate) fn new_v1_key_marker( key_marker: Bytes ) -> KeyValueContinuationInternal

Create a V1 key marker value.

pub(crate) fn new_v1_end_marker() -> KeyValueContinuationInternal

Create a V1 end marker value.

Trait Implementations

impl Clone for KeyValueContinuationInternal

fn clone(&self) -> KeyValueContinuationInternal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Continuation for KeyValueContinuationInternal

fn to_bytes(&self) -> FdbResult<Bytes>

Serialize this continuation to a Bytes value.

fn is_begin_marker(&self) -> bool

Return whether this continuation is at the begin marker position.

fn is_end_marker(&self) -> bool

Return whether this continuation is at the end marker position.

impl Debug for KeyValueContinuationInternal

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

Formats the value using the given formatter.

impl PartialEq<KeyValueContinuationInternal> for KeyValueContinuationInternal

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<Bytes> for KeyValueContinuationInternal

type Error = FdbError

The type returned in the event of a conversion error.

fn try_from(continuation: Bytes) -> FdbResult<KeyValueContinuationInternal>

Performs the conversion.

impl TryFrom<KeyValueContinuationInternal> for Bytes

type Error = FdbError

The type returned in the event of a conversion error.

fn try_from( keyvalue_continuation_internal: KeyValueContinuationInternal ) -> FdbResult<Bytes>

Performs the conversion.
