Struct CutPressure 

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

Cut pressure: graph-derived isolation signal (ADR-132, DC-2).

High pressure triggers migration or split. Computed by the mincut crate within the DC-2 time budget (50 microseconds per epoch).

Implementations

impl CutPressure

pub const ZERO: Self

Zero pressure – no migration or split needed.

pub const DEFAULT_SPLIT_THRESHOLD: Self

Default split threshold. Partitions exceeding this are candidates for split.

pub const fn from_fixed(val: u32) -> Self

Create a cut pressure value from a fixed-point representation.

pub const fn as_fixed(self) -> u32

Return the raw fixed-point value.

pub const fn exceeds_threshold(self, threshold: Self) -> bool

Check whether this pressure exceeds the given threshold.

Inequality operator !=.

impl PartialOrd for CutPressure

fn partial_cmp(&self, other: &CutPressure) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.
