Module harness 

Harness template and source validation for Rust code execution.

This module contains the harness template that wraps user code, source validation functions, and output extraction utilities. These are shared between RustSandboxExecutor (legacy) and RustExecutor (new).

Constants

HARNESS_TEMPLATE

The harness template that wraps user code.

REJECTED_PATTERNS

Patterns that are rejected in user code because they conflict with the harness or exceed the phase 1 source model.

Functions

extract_structured_output

Extract structured JSON output from stdout.

strip_comments

Strip single-line (//) and block (/* */) comments from Rust source.

truncate_output

Truncate output to the given byte limit. Returns the (possibly truncated) string and whether truncation occurred.

validate_rust_source

Validate that user source code fits the phase 1 bounded source model.
