Struct FpsCounter 

pub struct FpsCounter {
    pub label: Option<AssetId>,
}

Requests a frames-per-second counter; optionally writes it to a TextLabel.

Declaring an FpsCounter updates the named TextLabel with the current rate once per second. Omit label to suppress on-screen display.

To display an FPS overlay, declare a Font, a TextLabel, and an FpsCounter that references the label:

Fields

label: Option<AssetId>

A TextLabel to update with the current FPS each second. Leave unset to suppress on-screen display.

Trait Implementations

impl Clone for FpsCounter

fn clone(&self) -> FpsCounter

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for FpsCounter

const NAME: &'static str = "FpsCounter"

The registry name a world authors this component under.

fn from_baked(bytes: &[u8]) -> Result<Self, CnResult>

Reconstruct this component from a blob record, whose bytes are the serialized runtime component (cook already ran the asset -> component translation). The default rejects: runtime-only components are never stored in a blob, so only loadable types provide an implementation.

fn inject_locator(&mut self, _locator: PayloadLocator)

Called after construction to inject the payload locator from the blob def. Only meaningful for components with a compiled payload. The default implementation does nothing (correct for most components).

fn inject_name(&mut self, _id: AssetId)

Called after construction to inject the asset’s identity from the blob def. Only meaningful for components that look themselves up by id at runtime. The default implementation does nothing.

impl ComponentSlot for FpsCounter

const DISCRIMINANT: u8

The component type’s stable id, used as its ComponentId.

fn slot(s: &ComponentStorage) -> &Column<Self>

Borrow this type’s column out of the storage.

fn slot_mut(s: &mut ComponentStorage) -> &mut Column<Self>

Mutably borrow this type’s column out of the storage.

impl Debug for FpsCounter

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

Formats the value using the given formatter.

impl Default for FpsCounter

fn default() -> FpsCounter

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FpsCounter

where FpsCounter: Default,

fn deserialize<__D>( __deserializer: __D, ) -> Result<FpsCounter, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<FpsCounter> for ComponentAsset

fn from(c: FpsCounter) -> Self

Converts to this type from the input type.

impl RuntimeComponent for FpsCounter

impl Serialize for FpsCounter

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
