Struct ProviderCrash 

pub struct ProviderCrash {
    pub lines: Vec<String>,
    pub signal: Option<i32>,
}

A typed summary of a provider subprocess crash, assembled from the captured stderr/stdout crash-signal lines (and, best-effort, the process exit signal). Returned by Plugin::crash_summary iff any crash-signal line was seen. The operator’s anomaly classifier matches the typed EngineError::ProviderCrashed this enriches, never a substring.

Fields

lines: Vec<String>

The crash-signal lines captured from the provider’s stderr/stdout, in arrival order (e.g. panic: runtime error: ..., goroutine 1 [running]:).

signal: Option<i32>

The unix signal the subprocess died from, if observed via try_wait() before Drop reaped it (11 = SIGSEGV). Best-effort confirmation; None when unobserved or non-unix.

Implementations

impl ProviderCrash

pub fn crash_site(&self) -> Option<String>

The first captured backtrace frame that names a Go source location (…/file.go:NNN) — the actual crash SITE. This is the single most useful line for root-causing a provider panic: it names the file + line that nil-deref’d (e.g. a data source’s Read whose API client was never built). None when only the header was captured (no backtrace, or frames arrived past the ring window). The leading +0x… PC offset is trimmed — the file:line is the meaning.

pub fn headline(&self) -> Option<&str>

The most human-meaningful single line: the panic: / [signal …] header if present, else the first captured line. Used by the RPC error builder; None only when no line was captured at all.
