Struct ExecutionResult 

pub struct ExecutionResult {
    pub stdout: String,
    pub stderr: String,
    pub exit: Option<i32>,
    pub final_value: Option<String>,
    pub timed_out: bool,
}

The normalized outcome of running learner code to completion or timeout.

The observable channels are kept in distinct fields rather than one merged buffer (§1.2): a later grading prompt reads stdout and stderr independently and must never see one bleed into the other. An ExecutionResult only ever represents a process that actually ran — a failure to launch the interpreter is a RunnerError, never a value here.

Fields

stdout: String

Everything the program wrote to standard output.

stderr: String

Everything the program wrote to standard error.

exit: Option<i32>

The process exit code, or None when it was terminated by a signal (e.g. killed on timeout).

final_value: Option<String>

The final evaluated expression’s value, reserved for the grading prompt. None until its producer lands with grading (Slice 9, ADR-0005).

timed_out: bool

Whether the run was killed for exceeding its Timeout.

Trait Implementations

impl Clone for ExecutionResult

fn clone(&self) -> ExecutionResult

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExecutionResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ExecutionResult

fn eq(&self, other: &ExecutionResult) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
