pub struct HotLoopDetector {
pub window_secs: u64,
pub min_restarts: u32,
pub crash_times: Vec<u64>,
}Expand description
Hot loop detector for identifying rapid crash-restart cycles.
Detects when a child crashes and restarts too frequently within a sliding time window, indicating a potential hot loop condition that requires protective intervention.
Fields§
§window_secs: u64Sliding time window in seconds for detecting hot loops.
min_restarts: u32Minimum number of restarts within window to trigger detection.
crash_times: Vec<u64>Timestamps of recent crashes (Unix epoch seconds).
Implementations§
Source§impl HotLoopDetector
impl HotLoopDetector
Sourcepub fn new(window_secs: u64, min_restarts: u32) -> Self
pub fn new(window_secs: u64, min_restarts: u32) -> Self
Creates a new hot loop detector.
§Arguments
window_secs: Sliding time window in seconds.min_restarts: Minimum restarts within window to trigger detection.
§Returns
Returns a new HotLoopDetector with empty crash history.
§Examples
use rust_supervisor::policy::backoff::HotLoopDetector;
let detector = HotLoopDetector::new(60, 5);
assert!(!detector.is_hot_loop_detected(1000));Sourcepub fn record_crash(&mut self, crash_time_secs: u64) -> bool
pub fn record_crash(&mut self, crash_time_secs: u64) -> bool
Records a crash event and checks if hot loop is detected.
§Arguments
crash_time_secs: Crash timestamp as Unix epoch seconds.
§Returns
Returns true if hot loop condition is detected, false otherwise.
§Examples
use rust_supervisor::policy::backoff::HotLoopDetector;
let mut detector = HotLoopDetector::new(60, 3);
detector.record_crash(1000);
detector.record_crash(1010);
detector.record_crash(1020);
assert!(detector.is_hot_loop_detected(1020)); // 3 crashes in 20 secondsSourcepub fn is_hot_loop_detected(&self, current_time_secs: u64) -> bool
pub fn is_hot_loop_detected(&self, current_time_secs: u64) -> bool
Sourcepub fn get_crash_count_in_window(&self, current_time_secs: u64) -> usize
pub fn get_crash_count_in_window(&self, current_time_secs: u64) -> usize
Sourcepub fn clear_history(&mut self)
pub fn clear_history(&mut self)
Clears the crash history, typically called after successful stable runtime.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().

painted.white();Source§fn bright_black(&self) -> Painted<&T>

fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.

renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
