Struct PlanCache 

pub struct PlanCache { /* private fields */ }

FFT Plan Cache with configurable size limits and TTL

Implementations

impl PlanCache

pub fn new() -> Self

Create a new plan cache with default settings

pub fn with_config(max_entries: usize, max_age: Duration) -> Self

Create a new plan cache with custom settings

pub fn set_enabled(&self, enabled: bool)

Enable or disable the cache

pub fn is_enabled(&self) -> bool

Check if the cache is enabled

pub fn clear(&self)

Clear all cached plans

pub fn get_stats(&self) -> CacheStats

Get statistics about cache usage

pub fn track_plan_usage(&self, size: usize, forward: bool)

Track FFT plan usage in the cache (OxiFFT backend)

Note: OxiFFT plans are managed globally via oxifft_plan_cache. This method provides tracking and statistics for plan usage.

pub fn precompute_common_sizes(&self, sizes: &[usize])

Pre-populate cache with common sizes (OxiFFT backend)

Note: With OxiFFT, plans are created lazily and cached globally. This method tracks sizes for statistics purposes.

Trait Implementations

impl Default for PlanCache

fn default() -> Self

Returns the “default value” for a type.
