Struct SDL_PenDeviceType 

#[repr(transparent)]
pub struct SDL_PenDeviceType(pub c_int);

An enum that describes the type of a pen device.

A “direct” device is a pen that touches a graphic display (like an Apple Pencil on an iPad’s screen). “Indirect” devices touch an external tablet surface that is connected to the machine but is not a display (like a lower-end Wacom tablet connected over USB).

Apps may use this information to decide if they should draw a cursor; if the pen is touching the screen directly, a cursor doesn’t make sense and can be in the way, but becomes necessary for indirect devices to know where on the display they are interacting.

Available Since: This enum is available since SDL 3.4.0.

Implementations

impl SDL_PenDeviceType

pub const SDL_PEN_DEVICE_TYPE_INVALID: SDL_PenDeviceType

< Not a valid pen device.

pub const SDL_PEN_DEVICE_TYPE_UNKNOWN: SDL_PenDeviceType

< Don’t know specifics of this pen.

pub const SDL_PEN_DEVICE_TYPE_DIRECT: SDL_PenDeviceType

< Pen touches display.

pub const SDL_PEN_DEVICE_TYPE_INDIRECT: SDL_PenDeviceType

< Pen touches something that isn’t the display.

Trait Implementations

impl Clone for SDL_PenDeviceType

fn clone(&self) -> SDL_PenDeviceType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SDL_PenDeviceType

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

Formats the value using the given formatter.

impl Hash for SDL_PenDeviceType

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 SDL_PenDeviceType

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