Struct Rungs 

pub struct Rungs {
    pub multi: usize,
    pub narrow: usize,
    pub wide: usize,
    pub enter: u32,
    pub leave: u32,
    pub dwell: u64,
}

2026-09-25: The resolver’s widths and thresholds. defaults and from_env clamp each width to 2..=max(cap, 2).

Fields

multi: usize

2026-09-25: K at C >= 2.

narrow: usize

2026-09-25: K at C = 1 in the narrow state.

wide: usize

2026-09-25: K at C = 1 in the wide state.

enter: u32

2026-09-25: Window hits at or above which C = 1 goes wide.

leave: u32

2026-09-25: Window hits at or below which C = 1 goes narrow.

dwell: u64

2026-09-25: Minimum single-stream verify steps between two switches.

Implementations

impl Rungs

pub fn defaults(cap: usize) -> Self

2026-09-25: The compiled defaults for a head whose widest verify width is cap.

pub fn from_env(cap: usize, woa_available: bool) -> Self

2026-09-25: The defaults with the environment overrides applied, and the C >= 2 rung at the cap when the write-on-accept kernel is off.

Trait Implementations

impl Clone for Rungs

fn clone(&self) -> Rungs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rungs

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

Formats the value using the given formatter.

impl PartialEq for Rungs

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