Struct scylla::transport::PagingState

pub struct PagingState(/* private fields */);

The state of a paged query, i.e. where to resume fetching result rows upon next request.

Cheaply clonable.

Implementations

impl PagingState

pub fn start() -> PagingState

A start state - the state of a not-yet-started paged query.

pub fn as_bytes_slice(&self) -> Option<&Arc<[u8]>>

Returns the inner representation of PagingState. One can use this to store paging state for a longer time, and later restore it using Self::new_from_raw_bytes. In case None is returned, this signifies PagingState::start() being underneath.

pub fn new_from_raw_bytes(raw_bytes: impl Into<Arc<[u8]>>) -> PagingState

Creates PagingState from its inner representation. One can use this to restore paging state after longer time, having previously stored it using Self::as_bytes_slice.

Trait Implementations

impl Clone for PagingState

fn clone(&self) -> PagingState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PagingState

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

Formats the value using the given formatter.

impl Default for PagingState

fn default() -> PagingState

Returns the “default value” for a type.

impl PartialEq for PagingState

fn eq(&self, other: &PagingState) -> 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.
