Struct TestExecutionStats 

pub struct TestExecutionStats {
    pub states_captured: u64,
    pub bytes_raw: u64,
    pub bytes_compressed: u64,
    pub same_fill_pages: u64,
    /* private fields */
}

Test execution statistics with compression metrics

Tracks game state capture efficiency during test runs. Based on trueno-zram compression statistics patterns.

Example

use jugar_probar::validators::TestExecutionStats;

let mut stats = TestExecutionStats::new();
stats.record_state_capture(4096, 1024);
stats.record_state_capture(4096, 512); // Same-fill page

assert!(stats.efficiency() > 0.5);

Fields

states_captured: u64

Total game states captured

bytes_raw: u64

Bytes before compression

bytes_compressed: u64

Bytes after compression

same_fill_pages: u64

Same-fill pages detected (high compression)
