Struct OutputCapturer 

pub struct OutputCapturer { /* private fields */ }

Output capturer for a single execution

Provides a simple interface for capturing output during code execution. Uses Arc<Mutex> internally to allow sharing across threads.

Implementations

impl OutputCapturer

pub fn new() -> Self

Create a new output capturer

pub fn capture_stdout(&self, output: &str)

Capture stdout

Appends the given string to the captured stdout.

pub fn capture_stderr(&self, output: &str)

Capture stderr

Appends the given string to the captured stderr.

pub fn get_output(&self) -> CapturedOutput

Get the captured output

pub fn clear(&self)

Clear all captured output

pub fn with_capture<F, R>(&self, f: F) -> R

where F: FnOnce() -> R,

Execute a function and capture its output

This is a helper for testing and will be used when we integrate with actual code execution.

Example

use oxur_repl::eval::output_capture::OutputCapturer;

let capturer = OutputCapturer::new();

let result = capturer.with_capture(|| {
    // Simulate some output
    capturer.capture_stdout("Hello, ");
    capturer.capture_stdout("world!\n");
    capturer.capture_stderr("Warning: test\n");
    42
});

assert_eq!(result, 42);
let output = capturer.get_output();
assert_eq!(output.stdout, "Hello, world!\n");
assert_eq!(output.stderr, "Warning: test\n");
