Struct PageInfo 

pub struct PageInfo { /* private fields */ }

Page occupancy information for a Salsa struct ingredient.

Empty pages are excluded. Page fill is the number of slots that have been initialized, so slots remain included after their values are deleted or made available for reuse. Percentiles use the nearest-rank method across the ingredient’s non-empty pages.

Implementations

impl PageInfo

pub fn page_count(&self) -> usize

Returns the number of non-empty pages allocated for this ingredient.

pub fn page_capacity(&self) -> usize

Returns the number of slots that can be stored in each page.

pub fn excess_capacity(&self) -> usize

Returns the number of unused slots across all non-empty pages.

pub fn p25_fill(&self) -> usize

Returns the 25th percentile of initialized slots per non-empty page.

pub fn p50_fill(&self) -> usize

Returns the 50th percentile of initialized slots per non-empty page.

pub fn p75_fill(&self) -> usize

Returns the 75th percentile of initialized slots per non-empty page.

pub fn p90_fill(&self) -> usize

Returns the 90th percentile of initialized slots per non-empty page.

pub fn p99_fill(&self) -> usize

Returns the 99th percentile of initialized slots per non-empty page.
