Enum SnapshotSupport 

pub enum SnapshotSupport {
    Enabled,
    Disabled,
}

Declares whether a component supports snapshot persistence.

Components use this to declare their snapshot capability. The engine uses this to determine how to handle snapshot operations.

Variants

Enabled

Component supports and requires snapshot persistence.

• snapshot() will be called during session save
• restore() will be called during session load
• Restore failure is an error (not a warning)

Disabled

Component does not support snapshots (default).

• snapshot() and restore() will NOT be called
• If called anyway, returns SnapshotError::NotSupported

Trait Implementations

impl Clone for SnapshotSupport

fn clone(&self) -> SnapshotSupport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SnapshotSupport

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

Formats the value using the given formatter.

impl Default for SnapshotSupport

fn default() -> SnapshotSupport

Returns the “default value” for a type.

impl PartialEq for SnapshotSupport

fn eq(&self, other: &SnapshotSupport) -> 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 Copy for SnapshotSupport

impl Eq for SnapshotSupport

impl StructuralPartialEq for SnapshotSupport
