Errors that can occur while resolving a container name to a PID.

Variants

RuntimeNotFound

The container runtime CLI needed for this backend is not installed.

Fields

runtime: &'static str

tool: &'static str

CommandFailedToRun

Spawning the runtime CLI failed.

Fields

command: String

source: Error

CommandFailed

The runtime CLI ran but exited with an error.

Fields

command: String

status: String

stderr: String

UnexpectedOutput

The runtime CLI produced output we could not parse.

Fields

command: String

message: String

InvalidPid

The runtime reported a PID that is not a number.

Fields

pid: String

runtime: &'static str

container: String

source: ParseIntError

NotRunning(String)

The container exists but is not running.

ContainerNotFound

No container matched the given name/ID for this backend.

Fields

container: String

message: String

Io

Reading a file or directory failed.

Fields

path: PathBuf

source: Error

InvalidProcessId(String, ParseIntError)

The given container ID is not a valid process ID.

NoSuchProcess(RawPid)

No process with the given PID exists.

NoRuntimeMatched

None of the tried container runtimes could resolve the container.

Fields

container: String

tried: String

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.
