Enum ErrorKind

    FsError,
    Common(String),
    WriteFailed(String, String),
    ReadFailed(String),
    RemoveFailed,
    ParseError,
    InvalidOperation,

}

The different types of errors that can occur while manipulating control groups.

Variants

FsError

Common(String)

WriteFailed(String, String)

An error occured while writing to a control group file.

ReadFailed(String)

An error occured while trying to read from a control group file.

RemoveFailed

An error occured while trying to remove a control group.

ParseError

An error occured while trying to parse a value from a control group file.

In the future, there will be some information attached to this field.

InvalidOperation

You tried to do something invalid.

This could be because you tried to set a value in a control group that is not a root control group. Or, when using unified hierarchy, you tried to add a task in a leaf node.

InvalidPath

The path of the control group was invalid.

This could be caused by trying to escape the control group filesystem via a string of “..”. This crate checks against this and operations will fail with this error.

InvalidBytesSize

SpecifiedControllers

The specified controller is not in the list of supported controllers.

CgroupVersion

Using method in wrong cgroup version.

CgroupMode

Using method in wrong cgroup mode.

SubsystemsEmpty

Subsystems is empty.

Other

An unknown error has occured.

Trait Implementations

impl Debug for ErrorKind

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

Formats the value using the given formatter.

impl Display for ErrorKind

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

Formats the value using the given formatter.

impl Eq for ErrorKind

impl Error for ErrorKind

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 PartialEq for ErrorKind

fn eq(&self, other: &ErrorKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
