Enum Error 

pub enum Error {
    Unavailable {
        reason: String,
    },
    Failed {
        command: String,
        status: ExitStatus,
        stderr: String,
    },
    Parse {
        command: String,
        source: Error,
    },
    Io {
        command: String,
        source: Error,
    },
}

What can go wrong driving a ComposeEngine.

Fields

reason: String

Why, as the CLI or the OS put it.

Failed

A command ran and failed.

Fields

command: String

The command line, without the program (e.g. compose up -d --wait).

status: ExitStatus

Its exit status.

stderr: String

What it printed on stderr, when it was captured.

Parse

A command’s output didn’t parse as expected.

Fields

command: String

The command line, without the program.

source: Error

The JSON error.

Io

Spawning or talking to a command failed for another reason.

Fields

command: String

The command line, without the program.

source: Error

The I/O error.

Implementations

impl Error

pub fn is_unavailable(&self) -> bool

Whether this is Error::Unavailable.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for InstanceError

fn from(source: Error) -> Self

Converts to this type from the input type.
