Struct ParallelWalControlSurface 

pub struct ParallelWalControlSurface {
    pub mode: ParallelWalOperatingMode,
    pub lane_count_override: Option<usize>,
    pub helper_lane_budget: Option<usize>,
    pub max_parallel_commit_bytes: Option<u64>,
    pub max_flush_delay_ms: Option<u64>,
    pub shadow_compare_sampling_per_mille: Option<u16>,
}

Explicit operator control surface for the D1.a contract.

This is intentionally configuration-shaped rather than implementation- shaped so the later D1.b/D1.c/D1.d beads cannot reinterpret the runtime knobs ad hoc.

Fields

mode: ParallelWalOperatingMode

Auto, Conservative, or ShadowCompare.

lane_count_override: Option<usize>

Optional hard override for the number of active append lanes.

helper_lane_budget: Option<usize>

Optional cap for helper/combine lanes assisting with flush work.

max_parallel_commit_bytes: Option<u64>

Optional cap on batch bytes the decision plane may stage before sealing.

max_flush_delay_ms: Option<u64>

Optional cap on how long a batch may wait before being sealed/flushed.

shadow_compare_sampling_per_mille: Option<u16>

Shadow-compare sampling rate in per-mille. None disables sampling.

Trait Implementations

impl Clone for ParallelWalControlSurface

fn clone(&self) -> ParallelWalControlSurface

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParallelWalControlSurface

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

Formats the value using the given formatter.

impl Default for ParallelWalControlSurface

fn default() -> Self

Returns the “default value” for a type.

impl Eq for ParallelWalControlSurface

impl PartialEq for ParallelWalControlSurface

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