Struct RopeSpec 

pub struct RopeSpec {
    pub q: Symbol,
    pub rc: Symbol,
    pub rs: Symbol,
    pub out: Symbol,
    pub h: usize,
    pub half: usize,
    pub hd: usize,
    pub rows: usize,
    pub from: Option<(RowIndex, usize)>,
}

Qr = rope(Q, cos, sin) — RoPE-NEOX over h heads of hd dims, rotating each head’s leading 2·half dims as (i, i+half) pairs and passing the remaining hd − 2·half through (Qwen3.8’s partial rotary; hd == 2·half is the classic full form). hd is read off the pass-through loop’s bound.

Fields

q: Symbol

rc: Symbol

rs: Symbol

out: Symbol

h: usize

half: usize

hd: usize

rows: usize

The tables’ rows: 1 — every head turns by the one row of angles — or one per row of Q, head v turning by table row v / (h / rows). With from, the rows of Q.

from: Option<(RowIndex, usize)>

from position P: the tables are a cache of angles for this many positions, and row r of Q (0-based) turns by cache row P + r (1-based) — P checked to keep the block’s rows among the cache’s.

Trait Implementations

impl Clone for RopeSpec

fn clone(&self) -> RopeSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RopeSpec

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

Formats the value using the given formatter.

impl PartialEq for RopeSpec

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