Implementations

impl FusionReport

pub fn analyze(before: &Graph, after: &Graph) -> FusionReport

Compare an unfused graph with the post-pass result.

pub fn scan(graph: &Graph) -> FusionReport

Scan a graph (typically post-fusion) for patterns that should have collapsed but did not.

pub fn missed_matmul_bias_act(&self) -> usize

pub fn missed_swiglu(&self) -> usize

pub fn missed_shared_matmul(&self) -> usize

pub fn summary_line(&self) -> String

One-line summary suitable for logs and CSV benches.

Trait Implementations

impl Clone for FusionReport

fn clone(&self) -> FusionReport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FusionReport

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

Formats the value using the given formatter.

impl Default for FusionReport

fn default() -> FusionReport

Returns the “default value” for a type.

impl Display for FusionReport

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

Formats the value using the given formatter.

impl Eq for FusionReport

impl PartialEq for FusionReport

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