Struct PageCursor 

pub struct PageCursor { /* private fields */ }

A serializable continuation bound to the original operation and request.

Treat persisted cursors as opaque values. Validation runs again when used.

Implementations

impl PageCursor

pub fn provider(&self) -> Provider

Provider to which this continuation belongs.

pub fn continuation(provider: Provider, target: String) -> Self

A continuation for an adapter to return in ProviderPage::next.

provider must be the adapter’s own id and target is whatever state the adapter needs to fetch the next page. The routing layer binds the cursor to the operation and request, and checks both before handing it back.

pub fn target(&self) -> &str

The adapter state passed to continuation.
