Struct zng_view_api::window::FrameWaitId

pub struct FrameWaitId(/* private fields */);

Identifies a frame request for collaborative resize in WindowChanged.

The View Process defines the ID.

Implementations

impl FrameWaitId

pub const INVALID: Self = _

Dummy ID, zero.

pub const fn first() -> Self

Create the first valid ID.

pub const fn next(self) -> Self

Create the next ID.

IDs wrap around to first when the entire u32 space is used, it is never INVALID.

pub fn incr(&mut self) -> Self

Returns self and replace self with next.

pub const fn get(self) -> u32

Get the raw ID.

pub const fn from_raw(id: u32) -> Self

Create an ID using a custom value.

Note that only the documented process must generate IDs, and that it must only generate IDs using this function or the next function.

If the id is zero it will still be INVALID and handled differently by the other process, zero is never valid.

Trait Implementations

impl Clone for FrameWaitId

fn clone(&self) -> FrameWaitId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FrameWaitId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FrameWaitId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FrameWaitId

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 FrameWaitId

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FrameWaitId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
