Enum ChildFailure 

pub enum ChildFailure {
    Files(String),
    Start(String),
    Wait(String),
    TimedOut(Duration),
    TooLarge {
        stream: &'static str,
        limit: usize,
    },
}

What: Why a child produced no usable result. String carries the operating system’s own words where it gave any. Why: Each cause gets its own sentence for the person who ran the command.

In TS you’d write (pseudocode):

type ChildFailure = { kind: 'files' | 'start' | 'wait'; reason: string } | { kind: 'timed-out' } | { kind: 'too-large'; stream: string; limit: number };

Variants

Files(String)

A temporary file for the child’s streams could not be made or used.

Tuple Fields

0: String

The operating system’s reason.

Start(String)

The child could not be started.

Tuple Fields

0: String

The operating system’s reason.

Wait(String)

The child could not be waited for.

Tuple Fields

0: String

The operating system’s reason.

TimedOut(Duration)

The child was still running at its time bound and was killed.

Tuple Fields

0: Duration

The bound it exceeded.

TooLarge

The child wrote more than its cap to one stream and was killed.

Fields

stream: &'static str

standard output or standard error.

limit: usize

The cap it exceeded, in bytes.
