crashtrack (Rust client)

Lightweight Windows crash reporter. Installs an unhandled-exception filter that writes a minidump on crash, and uploads queued dumps to a crashtrack server on the next launch.

Add it

[dependencies]
crashtrack = "0.1"

Use it

use crashtrack::Config;

fn main() {
    crashtrack::install(Config {
        api_key:  "ct_pk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
        app:      "myapp",
        version:  env!("CARGO_PKG_VERSION"),
        endpoint: "https://api.crashtrack.dev",
    }).expect("crashtrack install");

    // ... rest of your program
}

Get an API key at https://crashtrack.dev (create a project, copy the key from settings).

What it does

On install: sets SetUnhandledExceptionFilter and spawns a background thread that scans %LOCALAPPDATA%/<app>/crashtrack/pending and uploads any queued minidumps from previous crashes.
On crash: the filter calls MiniDumpWriteDump and writes the dump to the pending directory, then returns EXCEPTION_CONTINUE_SEARCH so Windows Error Reporting still runs and the process terminates as normal.

The crash is uploaded the next time the app starts. This is intentional — the network stack is unreliable inside an exception filter.

Tradeoffs

Self-hosting: the server is open source — point endpoint at your own deployment if you don't want crashes going to crashtrack.dev.
Stack overflow: not covered by SetUnhandledExceptionFilter. v0.2 will add a vectored exception handler + guard-page recovery for that case.
OOM at crash time: the dump buffer is allocated lazily today. If the crash is from heap exhaustion the dump may fail to write. v0.2 will pre-allocate.
