Enum TouchEventType

#[repr(u32)]
pub enum TouchEventType {
    Started = 0,
    Move = 1,
    RelativeMove = 2,
    Ended = 3,
    Still = 4,
}

Touch event type.

Variants

Started = 0

Every time a user touches the screen a new Started event is generated

Move = 1

After a Started event has been emitted, there may be zero or more Move events when the finger is moved.

RelativeMove = 2

Relative move for touch is deprecated - relative events mainly make sense for mouse (since they can still happen when the mouse hits the screen edge - no such thing for touch).

Ended = 3

When the finger is lifted, an Ended event is generated

Still = 4

TODO: deprecate as it is no longer supported by the higher level API

Trait Implementations

impl CheckedBitPattern for TouchEventType

type Bits = u32

Self must have the same layout as the specified Bits except for the possible invalid bit patterns being checked during is_valid_bit_pattern.

fn is_valid_bit_pattern(bits: &Self::Bits) -> bool

If this function returns true, then it must be valid to reinterpret bits as &Self.

impl Clone for TouchEventType

fn clone(&self) -> TouchEventType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TouchEventType

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

Formats the value using the given formatter.

impl From<TouchEventType> for u32

fn from(enum_value: TouchEventType) -> Self

Converts to this type from the input type.

impl PartialEq for TouchEventType

fn eq(&self, other: &TouchEventType) -> 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 TryFrom<u32> for TouchEventType

type Error = TryFromPrimitiveError<TouchEventType>

The type returned in the event of a conversion error.

fn try_from(number: u32) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for TouchEventType

const NAME: &'static str = "TouchEventType"

type Primitive = u32

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>

impl Copy for TouchEventType

impl Eq for TouchEventType

impl NoUninit for TouchEventType

impl StructuralPartialEq for TouchEventType
