Available on crate feature test-helpers only.

An error type for test helpers.

This enum covers all failures that can occur during cgroup setup, network namespace creation, and link manipulation in integration tests.

Variants

Io

A filesystem operation failed (open, create, write, remove, etc.).

Fields

op: &'static str

The operation that failed (e.g. "create dir").

path: PathBuf

The path involved in the operation.

source: Error

Source error.

MissingMountEntryField

A mount entry is missing a required field (e.g. device, mountpoint, or fstype).

Fields

field: &'static str

The name of the missing field (e.g. "device", "mountpoint", "fstype").

mount_entry: String

The full mount entry line that is missing the field.

Cgroup2NotFound

No cgroup2 mount entry was found.

Syscall

A syscall failed.

Fields

syscall: &'static str

The syscall that failed (e.g. "nix::sched::unshare").

path: Option<PathBuf>

The path involved in the syscall, if any.

source: Errno

Source error.

Multi(Vec<Self>)

Multiple errors.

Netlink(NetlinkError)

An error occurred during a netlink operation.

Trait Implementations

impl Debug for AyaTestError

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

Formats the value using the given formatter.

impl Display for AyaTestError

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

Formats the value using the given formatter.

impl Error for AyaTestError

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<NetlinkError> for AyaTestError

fn from(source: NetlinkError) -> Self

Converts to this type from the input type.
