Struct DataLocalityInfo 

pub struct DataLocalityInfo {
    pub accesses: Vec<MemoryAccess>,
    pub working_set_bytes: u64,
    pub best_cache_level: CacheLevel,
    pub reuse_distance: f64,
}

Summary of data locality characteristics for a function or loop body.

Fields

accesses: Vec<MemoryAccess>

All memory accesses captured for this scope.

working_set_bytes: u64

Estimated working set size in bytes.

best_cache_level: CacheLevel

The cache level that best accommodates the working set.

reuse_distance: f64

Estimated average reuse distance (in number of intervening accesses).

Implementations

impl DataLocalityInfo

pub fn fits_in_l1(&self) -> bool

Returns true if the working set fits in L1 cache.

pub fn fits_in_l2(&self) -> bool

Returns true if the working set fits in L2 cache.

pub fn cache_friendly_fraction(&self) -> f64

Returns the fraction of accesses that are cache-friendly.
