Errors produced by sandbox operations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CgroupUnavailable(String)

cgroup v2 is not available on this system (non-systemd or pre-unified hierarchy kernel).

CgroupIo(Error)

A filesystem I/O error occurred while manipulating cgroupfs.

CgroupNotWritable

The discovered cgroup path is not writable by the current user.

Fields

path: String

The cgroup path that was found but could not be written to.

CgroupParseFailed(String)

Failed to parse /proc/self/cgroup.

RegistryFull

A process registry limit was exceeded.

Fields

max_tracked: usize

The configured limit.

ProcessNotFound

The requested PID was not found in the registry.

Fields

pid: u32

The process ID that was not found.

RuntimeNotFound

No OCI container runtime could be found on $PATH.

Fields

name: String

Name of the binary that was searched for.

RuntimeFailed

The container runtime exited with a non-zero status or failed to start.

Fields

reason: String

Human-readable reason.

SignalFailed

A signal could not be sent to the target process.

Fields

pid: u32

Target process ID.

reason: String

OS error message.

ApprovalDenied

An approval callback denied the operation.

Fields

operation: String

The operation that was denied.

SerdeError(Error)

Serialization or deserialization error when communicating with the init binary.

Unsupported(String)

Generic platform error for unsupported operations.

Trait Implementations

impl Debug for SandboxError

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

Formats the value using the given formatter.

impl Display for SandboxError

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

Formats the value using the given formatter.

impl Error for SandboxError

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 SandboxError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for SandboxError

fn from(source: Error) -> Self

Converts to this type from the input type.
