    InvalidPreviousPage,
    InvalidNextPage,
    InvalidLastPage,
    UnexpectedPage,

}

Pagination validation or transition error.

Variants

PageZero

Page numbers are one-based.

PerPageZero

Per-page values are one-based.

PageLimitZero

The caller-selected page limit must be nonzero.

InvalidPreviousPage

The previous-page link is not immediately before the current page.

InvalidNextPage

The next-page link is not immediately after the current page.

InvalidLastPage

The last page contradicts the current page or continuation state.

UnexpectedPage

The response page differs from the page the cursor requested.

EmptyPageWithNextPage

A non-terminal empty page advertised another page.

InvalidEntryCount

The decoded entry count contradicts page or total-entry metadata.

PageSizeChanged

Response page size differs from the caller-bound request size.

TraversalChanged

Total entries or last page changed during one traversal.

PageLimitExceeded

Advancing would exceed the caller-selected page limit.

Complete

The cursor already reached its terminal page.

Trait Implementations

impl Clone for PaginationError

fn clone(&self) -> PaginationError

impl Eq for PaginationError

impl Error for PaginationError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for PaginationError

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

Equality operator ==.

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

Inequality operator !=.
