Implementations

impl OpHistogram

pub fn total(&self) -> u32

pub fn is_empty(&self) -> bool

True iff every category is zero. The kernel has no ops at all.

pub fn dominant(&self) -> Option<(&'static str, u32)>

The dominant category and its count. Returns None if the histogram is empty. Useful for one-line “this kernel is mostly X” reporting.

pub fn is_memory_bound(&self) -> bool

True iff the kernel is dominated by memory ops (memory > all other categories combined). Memory-bound kernels typically benefit most from coalesce / vec_pack / shared-mem promotion.

pub fn is_arithmetic_bound(&self) -> bool

True iff the kernel is dominated by arithmetic ops. ALU-bound kernels benefit from strength_reduce / fma fusion / tensor cores.

pub fn merge(&mut self, other: OpHistogram)

Merge another histogram into self (saturating-adds every category). Useful for corpus-level rollup.

pub fn zero() -> Self

Identity element for Self::merge - all zeros. Default produces the same value but zero() reads more naturally as a fold seed.

pub fn format_short(&self) -> String

One-line human-readable summary suitable for log lines. Format: "N ops: lit=X arith=Y mem=Z cf=W sg=V bi=U other=T".
