Struct CrossArmRedundancy 

pub struct CrossArmRedundancy {
    pub redundant_pairs: Vec<(usize, usize, usize)>,
    pub total_redundant_ops: usize,
}

Report of cross-arm redundancy in a megakernel arm sequence.

Each pair (early, late) means arm late emits a MegakernelWorkItem that is structurally identical to one already emitted by arm early (and that arm has not been overwritten since). The runtime can drop the late arm’s redundant op and rewire its readers to the early arm’s output handle.

Fields

redundant_pairs: Vec<(usize, usize, usize)>

(early_arm_index, late_arm_index, redundant_op_index_in_late_arm). early_arm_index < late_arm_index always; the late arm is the one whose op is redundant.

total_redundant_ops: usize

Total redundant ops detected across the whole sequence. Equal to redundant_pairs.len() but exposed separately so the dispatcher can budget telemetry without scanning the vec.

Implementations

impl CrossArmRedundancy

pub fn new() -> Self

Empty report - no redundancy across arms.

pub fn is_empty(&self) -> bool

Whether this report names any opportunity.

Trait Implementations

impl Clone for CrossArmRedundancy

fn clone(&self) -> CrossArmRedundancy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CrossArmRedundancy

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

Formats the value using the given formatter.

impl Default for CrossArmRedundancy

fn default() -> CrossArmRedundancy

Returns the “default value” for a type.

impl Eq for CrossArmRedundancy

impl PartialEq for CrossArmRedundancy

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