Struct TouchConfig 

#[non_exhaustive]
pub struct TouchConfig {
    pub tap_area: DipSize,
    pub double_tap_area: DipSize,
    pub tap_max_time: Duration,
    pub double_tap_max_time: Duration,
    pub min_fling_velocity: Dip,
    pub max_fling_velocity: Dip,
}

System settings needed to implementing touch gestures.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

tap_area: DipSize

Maximum (x, y) distance between a touch start and end that generates a touch click.

Area can be disregarded if the touch is not ambiguous. This usually defines the initial lag for a single finger drag gesture.

double_tap_area: DipSize

Maximum (x, y) distance that a subsequent touch click is linked with the previous one as a double click.

Area can be disregarded if the touch is not ambiguous.

tap_max_time: Duration

Maximum time between start and end in the tap_area that generates a touch click.

Time can be disregarded if the touch is not ambiguous. This usually defines the long press delay.

double_tap_max_time: Duration

Maximum time between taps that generates a double click.

min_fling_velocity: Dip

Minimum velocity that can be considered a fling gesture, in dip per seconds.

max_fling_velocity: Dip

Fling velocity ceiling, in dip per seconds.

Implementations

impl TouchConfig

pub fn new( tap_area: DipSize, double_tap_area: DipSize, tap_max_time: Duration, double_tap_max_time: Duration, min_fling_velocity: Dip, max_fling_velocity: Dip, ) -> Self

New config.

Trait Implementations

impl Clone for TouchConfig

fn clone(&self) -> TouchConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TouchConfig

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

Formats the value using the given formatter.

impl Default for TouchConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TouchConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TouchConfig

fn eq(&self, other: &TouchConfig) -> 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 Serialize for TouchConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TouchConfig

impl Eq for TouchConfig

impl StructuralPartialEq for TouchConfig
