Struct LazyFactor 

pub struct LazyFactor { /* private fields */ }

Lazy factor that defers computation until needed.

Useful for chaining operations without intermediate allocations.

Implementations

impl LazyFactor

pub fn new<F>(computation: F) -> Self

where F: Fn() -> Result<Factor> + Send + Sync + 'static,

Create a new lazy factor from a computation.

pub fn from_factor(factor: Factor) -> Self

Create from an already computed factor.

pub fn evaluate(&self) -> Result<Factor>

Evaluate the lazy factor, computing if necessary.

pub fn is_computed(&self) -> bool

Check if the factor has been computed.

pub fn clear_cache(&self)

Clear cached result to free memory.

pub fn lazy_product(a: LazyFactor, b: LazyFactor) -> LazyFactor

Create a lazy product of two factors.

pub fn lazy_marginalize(factor: LazyFactor, var: String) -> LazyFactor
