Struct ConstPropStats 

pub struct ConstPropStats {
    pub arithmetic_folds: u64,
    pub comparison_folds: u64,
    pub boolean_folds: u64,
    pub nodes_before: u64,
    pub nodes_after: u64,
    pub passes: u32,
}

Statistics collected during a constant propagation run.

Fields

arithmetic_folds: u64

Number of arithmetic binary folding operations (e.g. Add(1,2) → 3, Mul(2,3) → 6).

comparison_folds: u64

Number of comparison folding operations (e.g. Lt(1,2) → True, Eq(3,3) → True).

boolean_folds: u64

Number of boolean/unary constant folding operations (e.g. Not(True) → False, Abs(-3) → 3).

nodes_before: u64

Total expression nodes counted before the first pass.

nodes_after: u64

Total expression nodes counted after the last pass.

passes: u32

Number of passes executed.

Implementations

impl ConstPropStats

pub fn total_folds(&self) -> u64

Total folds across all categories.

pub fn reduction_pct(&self) -> f64

Fraction of nodes removed: (before − after) / before.

Returns 0.0 when nodes_before == 0.

pub fn summary(&self) -> String

Human-readable one-line summary.

Trait Implementations

impl Clone for ConstPropStats

fn clone(&self) -> ConstPropStats

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConstPropStats

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

Formats the value using the given formatter.

impl Default for ConstPropStats

fn default() -> ConstPropStats

Returns the “default value” for a type.
