Struct SignWindow 

pub struct SignWindow<const W: usize> { /* private fields */ }

Fixed-capacity sliding window for computing sign tuples from a streaming residual sequence.

Generic parameter W is the drift-window width. All storage is stack-allocated: no heap, no unsafe, no std.

Implementations

impl<const W: usize> SignWindow<W>

pub const fn new() -> Self

Create an empty sliding window.

pub fn push(&mut self, norm: f64, below_floor: bool) -> SignTuple

Insert the next residual norm and return the current sign tuple.

When below_floor is true, the sample is stored (so future diffs see it) but drift and slew are forced to zero for this observation to avoid attributing structural meaning to noise-floor samples.

pub fn reset(&mut self)

Reset the window (e.g. after a context transition suppression period has ended).

pub fn count(&self) -> usize

The number of samples accumulated so far (saturates at W).

Trait Implementations

impl<const W: usize> Default for SignWindow<W>

fn default() -> Self

Returns the “default value” for a type.
