Expand description

Minimal host-side log sink for invoke diagnostics.

Production code uses StderrLogSink. Downstream test harnesses can implement this trait to capture and verify log content without touching stderr. Keeping this trait tiny avoids pulling in a full logging framework while still making the runtime’s only log call testable.

The sink receives a single pre-formatted message per invoke error. The message is constructed from the already-truncated InvokeError::detail, so a malicious 16 KiB guest error payload can never produce a 16 KiB log line.

Required Methods§

Source

fn emit(&self, message: &str)

Emit a single log line. The implementation decides where it goes.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
