Struct DrmDevice

pub struct DrmDevice(pub u64);

A Direct Rendering Manager (DRM) device.

It’s easiest to think of a DRM device as a graphics card. There are also DRM devices that are emulated in software but you are unlikely to encounter those accidentally.

Implementations

impl DrmDevice

pub fn connectors(self) -> Vec<Connector>

Returns the connectors of this device.

pub fn devnode(self) -> String

Returns the devnode of this device.

E.g. /dev/dri/card0.

pub fn syspath(self) -> String

Returns the syspath of this device.

E.g. /sys/devices/pci0000:00/0000:00:03.1/0000:07:00.0.

pub fn vendor(self) -> String

Returns the vendor of this device.

E.g. Advanced Micro Devices, Inc. [AMD/ATI].

pub fn model(self) -> String

Returns the model of this device.

E.g. Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (Radeon RX 570 Armor 8G OC).

pub fn pci_id(self) -> PciId

Returns the PIC ID of this device.

E.g. 1002:67DF.

pub fn make_render_device(self)

Makes this device the render device.

pub fn set_gfx_api(self, gfx_api: GfxApi)

Sets the preferred graphics API for this device.

If the API cannot be used, the compositor will try other APIs.

pub fn set_direct_scanout_enabled(self, enabled: bool)

Enables or disables direct scanout of client surfaces for this device.

pub fn set_flip_margin(self, margin: Duration)

Sets the flip margin of this device.

This is duration between the compositor initiating a page flip and the output’s vblank event. This determines the minimum input latency. The default is 1.5 ms.

Note that if the margin is too small, the compositor will dynamically increase it.

Trait Implementations

impl Clone for DrmDevice

fn clone(&self) -> DrmDevice

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DrmDevice

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DrmDevice

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for DrmDevice

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DrmDevice

fn eq(&self, other: &DrmDevice) -> 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.

impl Serialize for DrmDevice

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
