Struct CopyWindow 

pub struct CopyWindow { /* private fields */ }

2026-10-02: Copy window: how many tokens a copy may propose. It doubles after a copy is accepted in full and halves after one is cut short.

Implementations

impl CopyWindow

pub fn new(start: usize, min: usize, max: usize) -> Self

2026-10-02: A window starting at start, kept within [min, max] (1 <= min <= max).

pub fn current(&self) -> usize

2026-10-02: Tokens the next copy may propose.

pub fn record(&mut self, proposed: usize, accepted: usize)

2026-10-02: Updates the window after a copy of proposed tokens of which the first accepted matched the target.

Trait Implementations

impl Clone for CopyWindow

fn clone(&self) -> CopyWindow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CopyWindow

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

Formats the value using the given formatter.

impl PartialEq for CopyWindow

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