Struct DrmNode

pub struct DrmNode { /* private fields */ }

A node which refers to a DRM device.

Implementations

impl DrmNode

pub fn from_file<A: AsFd>(file: A) -> Result<DrmNode, CreateDrmNodeError>

Creates a DRM node from an open drm device.

pub fn from_path<A: AsRef<Path>>(path: A) -> Result<DrmNode, CreateDrmNodeError>

Creates a DRM node from path.

pub fn from_stat(stat: Stat) -> Result<DrmNode, CreateDrmNodeError>

Creates a DRM node from a file stat.

pub fn from_dev_id(dev: dev_t) -> Result<Self, CreateDrmNodeError>

Creates a DRM node from a [dev_t].

pub fn ty(&self) -> NodeType

Returns the type of the DRM node.

pub fn dev_id(&self) -> dev_t

Returns the device_id of the underlying DRM node.

pub fn dev_path(&self) -> Option<PathBuf>

Returns the path of the open device if possible.

pub fn dev_path_with_type(&self, ty: NodeType) -> Option<PathBuf>

Returns the path of the specified node type matching the device, if available.

pub fn node_with_type( &self, ty: NodeType, ) -> Option<Result<DrmNode, CreateDrmNodeError>>

Returns a new node of the specified node type matching the device, if available.

pub fn major(&self) -> u32

Returns the major device number of the DRM device.

pub fn minor(&self) -> u32

Returns the minor device number of the DRM device.

pub fn has_render(&self) -> bool

Returns whether the DRM device has render nodes.

Trait Implementations

impl Clone for DrmNode

fn clone(&self) -> DrmNode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DrmNode

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

Formats the value using the given formatter.

impl Display for DrmNode

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

Formats the value using the given formatter.

impl Hash for DrmNode

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 DrmNode

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