Struct OrbitEventCursor 

pub struct OrbitEventCursor { /* private fields */ }

Cursor for one event subscriber.

The cursor stores the next ring counter the subscriber should try to read. It is intentionally caller-owned so different consumers can advance independently.

Implementations

impl OrbitEventCursor

pub const fn from_start() -> Self

Start from the beginning of the ring history that is still available.

pub const fn from_counter(next_counter: u64) -> Self

Start from a known next counter.

pub const fn next_counter(self) -> u64

The next counter this cursor will read.

Trait Implementations

impl Clone for OrbitEventCursor

fn clone(&self) -> OrbitEventCursor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrbitEventCursor

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

Formats the value using the given formatter.

impl PartialEq for OrbitEventCursor

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