Enum ExecutionFailure 

pub enum ExecutionFailure {
    ExitStatus,
    TimedOut,
    Cancelled,
    OutputLimit {
        stream: OutputStream,
    },
    Io {
        operation: ExecutionOperation,
        source: Error,
    },
    Allocation {
        stream: OutputStream,
        source: TryReserveError,
    },
}

Why an invocation failed, independently of its retained output.

Variants

ExitStatus

The direct child completed unsuccessfully; its status is in evidence.

TimedOut

Child exit or pipe EOF was not observed before the caller’s deadline.

Cancelled

The caller’s cancellation predicate requested cleanup.

OutputLimit

A stream emitted more bytes than allowed.

Fields

stream: OutputStream

Stream whose bound was exceeded.

Io

A process or pipe operation failed.

Fields

operation: ExecutionOperation

Operation category; contains no command or credential values.

source: Error

Underlying typed failure.

Allocation

Retained output storage could not be allocated.

Fields

stream: OutputStream

Stream being captured.

source: TryReserveError

Underlying allocation failure.
