Enum PageChangeStatus 

pub enum PageChangeStatus {
    Unchanged,
    Modified,
    Added,
    Removed,
    Regressed,
}

Classification of a page’s change status between two snapshots.

Variants

Unchanged

LSN identical in both snapshots.

Modified

Current LSN is greater than base LSN.

Added

Page exists only in the current tablespace (tablespace grew).

Removed

Page exists only in the base tablespace (tablespace shrank).

Regressed

Current LSN is less than base LSN (unusual — possible point-in-time restore).

Trait Implementations

impl Clone for PageChangeStatus

fn clone(&self) -> PageChangeStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PageChangeStatus

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

Formats the value using the given formatter.

impl PartialEq for PageChangeStatus

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

impl Serialize for PageChangeStatus

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
