Struct ExecutionHistoryBaseline 

pub struct ExecutionHistoryBaseline {
    pub entry_count: usize,
    pub heap_size_bytes: usize,
    pub serialized_size_bytes: usize,
    pub tolerance: f64,
}

Performance baseline for execution history growth.

Fields

entry_count: usize

Number of entries in benchmark

heap_size_bytes: usize

Expected heap size in bytes

serialized_size_bytes: usize

Expected serialized size in bytes

tolerance: f64

Tolerance factor (1.2 = allow 20% deviation)

Implementations

impl ExecutionHistoryBaseline

pub const ENTRIES_1000: Self

Baseline for 1000 entries (default limit).

Measurement Methodology

These values are derived from benchmark tests that:

1. Create 1000 execution history entries with realistic content
2. Measure heap size using std::mem::size_of_val and content sizes
3. Serialize to JSON and measure compressed size
4. Run multiple iterations to verify consistency

Updating Baselines

If legitimate performance improvements reduce memory usage, update these values based on new benchmark measurements. Always maintain 20% tolerance to account for platform variance.

DO NOT increase these values to accommodate regressions. Investigate and fix the root cause instead.

pub fn check_heap_size(&self, measured: usize) -> Result<(), String>

Check if measured value exceeds baseline.

Errors

Returns error if the operation fails.

pub fn check_serialized_size(&self, measured: usize) -> Result<(), String>

Check if serialized size exceeds baseline.

Errors

Returns error if the operation fails.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for ExecutionHistoryBaseline

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