Struct Cache 

pub struct Cache<T> { /* private fields */ }

LRU cache keyed on dependency tags + scalar dependencies. T is the cached value type (Number, a Vec<Number>, an Rc<Vector>, …). Equivalent to Ipopt::CachedResults<T>.

Implementations

impl<T: Clone> Cache<T>

pub fn new(max_size: usize) -> Self

Bounded cache holding up to max_size entries.

pub fn unbounded() -> Self

Equivalent to Ipopt’s negative max_cache_size (no eviction).

pub fn clear(&mut self)

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn add( &mut self, value: T, dependents: &[&dyn TaggedObject], scalar_dependents: &[Number], )

Generic add — equivalent to AddCachedResult(result, dependents, scalar_dependents).

pub fn get( &self, dependents: &[&dyn TaggedObject], scalar_dependents: &[Number], ) -> Option<T>

Generic lookup — equivalent to GetCachedResult(...). Returns Some(value) if a stored entry’s dependency tags exactly match the current tags of dependents and the scalar deps match.

pub fn add_1dep(&mut self, value: T, dep: &dyn TaggedObject)

pub fn get_1dep(&self, dep: &dyn TaggedObject) -> Option<T>

pub fn add_2dep( &mut self, value: T, d1: &dyn TaggedObject, d2: &dyn TaggedObject, )

pub fn get_2dep( &self, d1: &dyn TaggedObject, d2: &dyn TaggedObject, ) -> Option<T>

pub fn add_3dep( &mut self, value: T, d1: &dyn TaggedObject, d2: &dyn TaggedObject, d3: &dyn TaggedObject, )

pub fn get_3dep( &self, d1: &dyn TaggedObject, d2: &dyn TaggedObject, d3: &dyn TaggedObject, ) -> Option<T>

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

Formats the value using the given formatter.
