Struct TuiLoadTest 

pub struct TuiLoadTest { /* private fields */ }

TUI Load Test Runner

Framework-agnostic load testing for TUI applications.

Implementations

impl TuiLoadTest

pub fn new() -> Self

Create a new TUI load test with default configuration

pub fn with_item_count(self, count: usize) -> Self

Create with specific item count

pub fn with_frame_budget_ms(self, budget_ms: f64) -> Self

Set frame budget in milliseconds

pub fn with_timeout_ms(self, timeout_ms: u64) -> Self

Set timeout for hang detection

pub fn with_filters(self, filters: Vec<String>) -> Self

Set filters to test

pub fn with_frames_per_filter(self, count: usize) -> Self

Set number of frames per filter

pub fn with_strict_budget(self, strict: bool) -> Self

Enable strict budget enforcement

pub fn data(&self) -> &[SyntheticItem]

Get the generated test data

pub fn config(&self) -> &TuiLoadConfig

Get configuration

pub fn run<F>(&self, render: F) -> TuiLoadResult<TuiFrameMetrics>

where F: FnMut(&[SyntheticItem], &str) -> Option<u64>,

Run load test with a render callback

The callback receives:

• items: Slice of synthetic items to render
• filter: Current filter string

The callback should perform the actual TUI rendering and return the frame time in microseconds, or None if it wants the test harness to measure time.

Errors

Returns error if a frame times out (hang detected) or exceeds budget in strict mode.

pub fn run_filter_stress<F>( &self, filter_fn: F, ) -> TuiLoadResult<Vec<(String, TuiFrameMetrics)>>

where F: FnMut(&[SyntheticItem], &str) -> Vec<SyntheticItem>,

Run filter-specific performance test

Tests filtering with increasing filter lengths to detect O(n²) or worse complexity in filter implementations.

Errors

Returns error if hang detected or budget exceeded.

Trait Implementations

impl Debug for TuiLoadTest

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

Formats the value using the given formatter.

impl Default for TuiLoadTest

fn default() -> Self

Returns the “default value” for a type.
