Struct Sequence 

pub struct Sequence(/* private fields */);

Monotonic event sequence number for change detection.

Each event processed by a driver is assigned a unique sequence number via World::next_sequence. Resources record the sequence at which they were last written. A resource is considered “changed” if its changed_at equals the world’s current_sequence. Wrapping is harmless — only equality is checked.

Trait Implementations

impl Clone for Sequence

fn clone(&self) -> Sequence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sequence

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

Formats the value using the given formatter.

impl Default for Sequence

fn default() -> Sequence

Returns the “default value” for a type.

impl Hash for Sequence

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Sequence

fn eq(&self, other: &Sequence) -> 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 Sequence

impl Eq for Sequence

impl StructuralPartialEq for Sequence
