Enum cgroups::error::ErrorKind

pub enum ErrorKind {
    WriteFailed,
    ReadFailed,
    ParseError,
    InvalidOperation,
    InvalidPath,
    Other,
}

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

Variants

WriteFailed

An error occured while writing to a control group file.

ReadFailed

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

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.

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 PartialEq<ErrorKind> for ErrorKind

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

This method tests for self and other values to be equal, and is used by ==.

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

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