}

The possible interaction dispositions that a client can respond with to a given |TouchPointerSample|. Used as part of a gesture disambiguation scheme.

The responses are based on the idea of an ownership claim on a interaction. Clients may assert a claim of ownership on an open interaction, but only one client’s claim is granted by the server; other clients’ claims are denied.

Variants

No = 1

The client has no further interest in this interaction; it declines ownership of the interaction. The client will stop receiving events for this interaction.

Maybe = 2

The client is interested in this interaction, but needs to see more events to decide; the client has not yet claimed ownership of this interaction.

MaybePrioritize = 3

The client is interested in this interaction, but needs to see more events to decide; the client has not yet claimed ownership of the interaction. During ownership resolution, it exerts its priority over lower-priority “maybe” claims, but always loses to a “yes” claim.

MaybeSuppress = 4

The client is interested in this interaction, but needs to see more events to decide; the client has not yet claimed ownership of the interaction. Moreover, it suppresses lower-priority claims that try to resolve interaction ownership.

MaybePrioritizeSuppress = 5

The client is interested in this interaction, but needs to see more events to decide; the client has not yet claimed ownership of the interaction. Moreover, it suppresses lower-priority claims that try to resolve interaction ownership. During ownership resolution, it exerts its priority over lower-priority “maybe” claims, but always loses to a “yes” claim.

Hold = 6

The client is interested in this interaction, but needs to see a subsequent interaction to decide; the client has not yet claimed ownership of this interaction. It prevents ownership resolution when the interaction closes.

HoldSuppress = 7

The client is interested in this interaction, but needs to see a subsequent interaction to decide; the client has not yet claimed ownership of this interaction. It prevents ownership resolution when the interaction closes. Moreover, it suppresses lower-priority claims that try to resolve interaction ownership.

Yes = 8

The client wishes exclusive access to the remaining events in this interaction; it claims ownership of this interaction (but that claim may be granted or denied). During ownership resolution, it yields its priority to lower-priority “yes” claims.

YesPrioritize = 9

The client wishes exclusive access to the remaining events in this interaction; it claims ownership of this interaction (but that claim may be granted or denied). During ownership resolution, it exerts its priority over lower-priority “yes” claims.

Implementations

impl TouchResponseType

pub fn from_primitive(prim: u32) -> Option<Self>

pub const fn into_primitive(self) -> u32

pub fn is_unknown(&self) -> bool

👎Deprecated: Strict enums should not use is_unknown

Trait Implementations

impl Clone for TouchResponseType

fn clone(&self) -> TouchResponseType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TouchResponseType

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

Formats the value using the given formatter.

impl<D: ResourceDialect> Decode<TouchResponseType, D> for TouchResponseType

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl<D: ResourceDialect> Encode<TouchResponseType, D> for TouchResponseType

unsafe fn encode( self, encoder: &mut Encoder<'_, D>, offset: usize, _depth: Depth, ) -> Result<()>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID.

impl Hash for TouchResponseType

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 TouchResponseType

fn cmp(&self, other: &TouchResponseType) -> 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 for TouchResponseType

fn eq(&self, other: &TouchResponseType) -> 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 PartialOrd for TouchResponseType

fn partial_cmp(&self, other: &TouchResponseType) -> 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

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

impl TypeMarker for TouchResponseType

type Owned = TouchResponseType

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for TouchResponseType

type Borrowed<'a> = TouchResponseType

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow(value: &<Self as TypeMarker>::Owned) -> Self::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
