Enum controlgroup::ErrorKind

pub enum ErrorKind {
    Io,
    Parse,
    InvalidArgument,
    InvalidOperation,
}

Kinds of errors that can occur while operating on cgroups.

Variants

Io

Failed to do an I/O operation on a cgroup file system.

Parse

Failed to parse a content of a cgroup file into a value.

In a future version, there will be some information attached to this variant.

InvalidArgument

You passed an invalid argument.

In a future version, this variant may have some information attached, or be replaced with more fine-grained variants.

Note that this crate catches not all errors caused by an invalid argument. In some cases, the system (kernel) raises an lower-level error, and this crate returns an Error with other ErrorKind, typically Io. The lower-level source can be obtained via Error::source method.

InvalidOperation

You tried to do something invalid.

In a future version, this variant may have some information attached, or be replaced with more fine-grained variants.

Note that this crate catches not all errors caused by an invalid operation. In some cases, the system (kernel) raises an lower-level error, and this crate returns an Error with other ErrorKind, typically Io. The lower-level source can be obtained via Error::source method.
