Enum NodeType

pub enum NodeType {
    Primary,
    Control,
    Render,
}

A type of node

Variants

Primary

A primary node may be used to allocate buffers.

If no other node is present, this may be used to post a buffer to an output with mode-setting.

Control

A control node may be used for mode-setting.

This is almost never used since no DRM API for control nodes is available yet.

Render

A render node may be used by a client to allocate buffers.

Mode-setting is not possible with a render node.

Implementations

impl NodeType

pub fn minor_name_prefix(&self) -> &'static str

Returns a string representing the prefix of a minor device’s name.

For example, on Linux with a primary node, the returned string would be card.

Trait Implementations

impl Clone for NodeType

fn clone(&self) -> NodeType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodeType

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

Formats the value using the given formatter.

impl Display for NodeType

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

Formats the value using the given formatter.

impl Hash for NodeType

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 NodeType

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