Struct ChildLimits 

pub struct ChildLimits {
    pub timeout: Duration,
    pub max_stdout: usize,
    pub max_stderr: usize,
}

What: The bounds of one child. usize is an unsigned size in bytes. #[derive(...)] generates copying, debug printing and ==. Why: The caller chooses them, so tests can use bounds small enough to reach quickly.

In TS you’d write (pseudocode):

type ChildLimits = { timeoutMs: number; maxStdout: number; maxStderr: number };

Fields

timeout: Duration

How long the child may run before it is killed.

max_stdout: usize

The most bytes of standard output kept; one more stops the child.

max_stderr: usize

The most bytes of standard error kept; one more stops the child.
