Struct evdi::device_node::DeviceNode

pub struct DeviceNode { /* fields omitted */ }

Represents a device node (/dev/dri/card*).

Implementations

impl DeviceNode

pub fn get() -> Option<Self>

Returns an evdi device node if one is available.

If no device is available you will need to run Device::add() with superuser permissions.

pub fn status(&self) -> DeviceNodeStatus

Check if a device node is an evdi device node, is a different device node, or doesn’t exist.

pub fn open(&self) -> Result<UnconnectedHandle, OpenDeviceError>

Open an evdi device node.

Returns None if we fail to open the device, which may be because the device isn’t an evdi device node.

pub fn list_available() -> Result<Vec<Self>>

List all evdi device nodes that have available status in a stable order

pub fn add() -> bool

Tell the kernel module to create a new evdi device node.

Requires superuser permissions.

pub fn remove_all() -> Result<()>

Remove all evdi device nodes.

Requires superuser permissions.

pub fn new(id: i32) -> Self

Create a struct representing /dev/dri/card{id}.

This does not create the device or check if the device exists.

Trait Implementations

impl Clone for DeviceNode

fn clone(&self) -> DeviceNode

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeviceNode

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

Formats the value using the given formatter.

impl Ord for DeviceNode

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

#[must_use]

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<DeviceNode> for DeviceNode

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

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

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

This method tests for !=.

impl PartialOrd<DeviceNode> for DeviceNode

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]

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

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

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

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
