Struct ListLanesPage 

#[non_exhaustive]
pub struct ListLanesPage {
    pub lanes: Vec<LaneId>,
    pub next_cursor: Option<LaneId>,
}

One page of lane ids returned by crate::engine_backend::EngineBackend::list_lanes.

Lanes are global (not partition-scoped) — the backend enumerates every registered lane, sorts by LaneId name, and returns a limit-sized slice starting after cursor (exclusive).

next_cursor is Some(last_lane_in_page) when more pages remain and None when the caller has read the final page. Callers that want the full list loop until next_cursor is None, threading the previous page’s next_cursor into the next call’s cursor argument.

#[non_exhaustive] — FF may add fields (e.g. a total hint) in minor releases without a semver break.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

lanes: Vec<LaneId>

The lanes in this page, sorted by LaneId name.

next_cursor: Option<LaneId>

Cursor for the next page (exclusive). None ⇒ final page.

Implementations

impl ListLanesPage

pub fn new(lanes: Vec<LaneId>, next_cursor: Option<LaneId>) -> Self

Construct a ListLanesPage. Present so downstream crates (ff-backend-valkey’s list_lanes impl) can assemble the struct despite the #[non_exhaustive] marker.

Trait Implementations

impl Clone for ListLanesPage

fn clone(&self) -> ListLanesPage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ListLanesPage

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

Formats the value using the given formatter.

impl PartialEq for ListLanesPage

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