Struct cgroups_rs::devices::DevicesController[][src]

pub struct DevicesController { /* fields omitted */ }

A controller that allows controlling the devices subsystem of a Cgroup.

In essence, using the devices controller, it is possible to allow or disallow sets of devices to be used by the control group’s tasks.

Implementations

impl DevicesController[src]

pub fn new(root: PathBuf) -> Self[src]

Constructs a new DevicesController with root serving as the root of the control group.

pub fn allow_device(
    &self,
    devtype: DeviceType,
    major: i64,
    minor: i64,
    perm: &[DevicePermissions]
) -> Result<()>
[src]

Allow a (possibly, set of) device(s) to be used by the tasks in the control group.

When -1 is passed as major or minor, the kernel interprets that value as “any”, meaning that it will match any device.

pub fn deny_device(
    &self,
    devtype: DeviceType,
    major: i64,
    minor: i64,
    perm: &[DevicePermissions]
) -> Result<()>
[src]

Deny the control group’s tasks access to the devices covered by dev.

When -1 is passed as major or minor, the kernel interprets that value as “any”, meaning that it will match any device.

pub fn allowed_devices(&self) -> Result<Vec<DeviceResource>>[src]

Get the current list of allowed devices.
