Struct CompilerPassStats 

pub struct CompilerPassStats {
    pub pass_id: CompilerPassId,
    pub wall_time: Duration,
    pub nodes_before: u64,
    pub nodes_after: u64,
    pub reductions: u64,
}

Timing and reduction statistics for a single pass execution.

Fields

pass_id: CompilerPassId

Which pass produced these stats.

wall_time: Duration

Wall-clock time spent in this pass.

nodes_before: u64

Node count immediately before the pass ran.

nodes_after: u64

Node count immediately after the pass completed.

reductions: u64

Number of reductions (folds, eliminations, inlines, rewrites, …).

Implementations

impl CompilerPassStats

pub fn reduction_pct(&self) -> f64

Fraction of nodes eliminated by this pass: (before − after) / before * 100.

Returns 0.0 when nodes_before == 0.

pub fn summary(&self) -> String

Human-readable one-line summary of this pass execution.

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

Performs copy-assignment from source.

impl Debug for CompilerPassStats

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