pub fn total(&self) -> f32

Trait Implementations

impl<T: DeserializeOwned + Send + Sync + 'static> Asset for Lottery<T>

type Loader = LoadFrom<Vec<(f32, T)>, RonLoader>

Specifies a way to convert raw bytes into the asset.

const EXTENSION: &'static str = "ron"

Use this field if your asset only uses one extension.

const EXTENSIONS: &'static [&'static str] = _

This field enables you to specify multiple extension for an asset.

fn default_value( id: &SharedString, error: Box<dyn Error + Send + Sync>, ) -> Result<Self, Box<dyn Error + Send + Sync>>

Specifies a eventual default value to use if an asset fails to load. If this method returns Ok, the returned value is used as an asset. In particular, if this method always returns Ok, AssetCache::load is guaranteed not to fail.

const HOT_RELOADED: bool = true

If false, disable hot-reloading for assets of this type (true by default). This avoids having to lock the asset to read it (ie it makes [Handle::read] a noop)

impl<T: Clone> Clone for Lottery<T>

fn clone(&self) -> Lottery<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Lottery<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Lottery<T>

where T: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<Vec<(f32, T)>> for Lottery<T>

fn from(items: Vec<(f32, T)>) -> Lottery<T>

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for Lottery<T>

fn eq(&self, other: &Lottery<T>) -> 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.
