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.

Availability

This enum is available since SDL 3.4.0.

Known values (sdl3-sys)

Associated constant	Global constant	Description
INVALID	SDL_PEN_DEVICE_TYPE_INVALID	Not a valid pen device.
UNKNOWN	SDL_PEN_DEVICE_TYPE_UNKNOWN	Don’t know specifics of this pen.
DIRECT	SDL_PEN_DEVICE_TYPE_DIRECT	Pen touches display.
INDIRECT	SDL_PEN_DEVICE_TYPE_INDIRECT	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

Available on crate feature debug-impls only.

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

Formats the value using the given formatter.

impl Default for SDL_PenDeviceType

fn default() -> SDL_PenDeviceType

Returns the “default value” for a type.

impl From<SDL_PenDeviceType> for c_int

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 Ord for SDL_PenDeviceType

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq<SDL_PenDeviceType> for c_int

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.

impl PartialEq<i32> for SDL_PenDeviceType

fn eq(&self, other: &c_int) -> 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 PartialEq for SDL_PenDeviceType

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

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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