Cache of optimized subexpressions

Implementations

impl GraphOptimizer

pub fn new() -> Self

pub fn optimize<T>(&mut self, node: ComputationNode<T>) -> ComputationNode<T>

where T: Shareable + Arithmetic + PartialEq + Clone,

Optimizes a computation graph by applying various transformations

pub fn eliminate_common_subexpressions<T>( &mut self, node: ComputationNode<T>, ) -> ComputationNode<T>

where T: Shareable,

Eliminates common subexpressions by reusing nodes with same structure

Trait Implementations

impl Default for GraphOptimizer

fn default() -> Self

Returns the “default value” for a type.
