Enum ParkEvent 

pub enum ParkEvent {
    Written,
    Replaced,
    Dropped,
}

What happened to one emitted park — the live progress hook’s event. A Replaced is NOT a new layer: it overwrote the previous park with a stronger frame, so it must not be counted as an additional park.

Variants

Written

A new distinct park frame was written (park_NNNNNN.jpg added).

Replaced

A stronger close pair superseded the previous park (overwritten, same layer).

Dropped

The park’s ring JPEG never arrived / the write failed — the frame is lost.

Trait Implementations

impl Clone for ParkEvent

fn clone(&self) -> ParkEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ParkEvent

impl Debug for ParkEvent

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

Formats the value using the given formatter.

impl Eq for ParkEvent

impl PartialEq for ParkEvent

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