Struct AdvancedSection 

pub struct AdvancedSection {

    pub tick_check_every: u32,
    pub ring_capacity: usize,
}

[advanced] section — reactor-loop tuning knobs that used to be hardcoded consts in kevy-rt. Defaults match the values shipped in workspace v1.3 / earlier so the existing benchmark numbers translate one-to-one. Tune only if you know what you’re doing (bench/REPORT.md documents the trade-offs).

Fields

spin_limit: u32

Iterations the per-core reactor spins on poll(timeout=0) before parking on a blocking wait. Higher = lower wake-up latency under contention, higher idle CPU; lower = the inverse. Default 256 (matches v1.0 const).

park_timeout_ms: u32

Bounded blocking wait in ms once the reactor parks. Acts as a safety backstop for any missed cross-core wake (the per-pair SeqCst fence is the primary mechanism since workspace v1.3.0). Default 50 ms.

tick_check_every: u32

How many reactor loop iterations between wall-clock reads for the tick (TTL reaper / auto-AOF-rewrite / live-config refresh). In busy-poll mode (~1M iter/s) the default 256 is one check per ~256 µs — plenty for a 10 Hz tick. In park mode the reactor bypasses this throttle (each iter is already ≥ 1 ms), so the value only matters under sustained load. Default 256.

ring_capacity: usize

Per-direction SPSC ring slot count (one ring per ordered core-pair). Must be a power of two; the ring code rounds up. Overflow spills to a local backlog Vec rather than blocking, so a small ring just shifts work to the slower path. Default 1024.

Trait Implementations

impl Clone for AdvancedSection

fn clone(&self) -> AdvancedSection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AdvancedSection

impl Debug for AdvancedSection

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

Formats the value using the given formatter.

impl Default for AdvancedSection

fn default() -> Self

Returns the “default value” for a type.

impl Eq for AdvancedSection

impl PartialEq for AdvancedSection

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