Struct AdaptiveSnapshotter 

pub struct AdaptiveSnapshotter {
    pub min_interval: u64,
    pub max_interval: u64,
    pub entropy_threshold: u32,
    /* private fields */
}

Adaptive snapshot scheduler based on state entropy.

Fixed-interval snapshots create Mura (unevenness):

• Menu screens waste space with identical snapshots
• High-action moments lack granularity

Solution: Snapshot based on state entropy (magnitude of change).

Fields

min_interval: u64

Minimum frames between snapshots.

max_interval: u64

Maximum frames between snapshots (force snapshot).

entropy_threshold: u32

Entropy threshold to trigger snapshot.

Implementations

impl AdaptiveSnapshotter

pub const fn new( min_interval: u64, max_interval: u64, entropy_threshold: u32, ) -> Self

Create with custom parameters.

pub fn should_snapshot( &mut self, frame: u64, state_hash: &[u8; 32], ) -> SnapshotDecision

Determine if a snapshot should be taken this frame.

pub const fn reset(&mut self)

Reset the snapshotter state.

pub const fn last_snapshot_frame(&self) -> u64

Get the frame of the last snapshot.
