Struct ColdStartLimiter 

pub struct ColdStartLimiter { /* private fields */ }

Tracks recent cold start attempts per URI to prevent DOS.

Uses rate limiting with a configurable minimum interval between cold start attempts for the same URI. This prevents malicious or buggy clients from overwhelming the server with rapid file loading requests.

Examples

use deps_lsp::document::ColdStartLimiter;
use tower_lsp_server::ls_types::Uri;
use std::time::Duration;

let limiter = ColdStartLimiter::new(Duration::from_millis(100));
let uri = Uri::from_file_path("/test.toml").unwrap();

assert!(limiter.allow_cold_start(&uri));
assert!(!limiter.allow_cold_start(&uri)); // Rate limited

Implementations

impl ColdStartLimiter

pub fn new(min_interval: Duration) -> Self

Creates a new cold start limiter with the specified minimum interval.

pub fn allow_cold_start(&self, uri: &Uri) -> bool

Returns true if cold start is allowed, false if rate limited.

Updates the last attempt time if the cold start is allowed.

pub fn cleanup_old_entries(&self, max_age: Duration)

Cleans up old entries periodically.

Removes entries older than max_age to prevent unbounded memory growth. Should be called from a background task.

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