Struct DceStats 

pub struct DceStats {
    pub constant_folds: u64,
    pub unreachable_branches: u64,
    pub unused_let_bindings: u64,
    pub total_nodes_before: u64,
    pub total_nodes_after: u64,
    pub passes: u32,
}

Statistics collected during a single or multi-pass DCE run.

Fields

constant_folds: u64

Number of constant-fold eliminations (And/Or/Not with constant operands).

unreachable_branches: u64

Number of unreachable branches eliminated (IfThenElse with constant condition).

unused_let_bindings: u64

Number of unused Let bindings removed.

total_nodes_before: u64

Total number of expression nodes before the first pass.

total_nodes_after: u64

Total number of expression nodes after the final pass.

passes: u32

Number of DCE passes that were executed.

Implementations

impl DceStats

pub fn reduction_ratio(&self) -> f64

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

Returns 0.0 when total_nodes_before == 0.

pub fn total_eliminations(&self) -> u64

Sum of all elimination counts across all categories.

pub fn summary(&self) -> String

Human-readable one-line summary of the DCE run.

Trait Implementations

impl Clone for DceStats

fn clone(&self) -> DceStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DceStats

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

Formats the value using the given formatter.

impl Default for DceStats

fn default() -> DceStats

Returns the “default value” for a type.
