Expand description

A dynamic type-erased counterpart to AssetMeta that enables passing around and interacting with AssetMeta without knowing its type.

Required Methods§

source

fn loader_settings(&self) -> Option<&(dyn Settings + 'static)>

Returns a reference to the AssetLoader settings, if they exist.

source

fn loader_settings_mut(&mut self) -> Option<&mut (dyn Settings + 'static)>

Returns a mutable reference to the AssetLoader settings, if they exist.

source

fn serialize(&self) -> Vec<u8> ⓘ

Serializes the internal AssetMeta.

source

fn processed_info(&self) -> &Option<ProcessedInfo>

Returns a reference to the ProcessedInfo if it exists.

source

fn processed_info_mut(&mut self) -> &mut Option<ProcessedInfo>

Returns a mutable reference to the ProcessedInfo if it exists.

Implementations§

source§

impl dyn AssetMetaDyn

source

pub fn is<__T>(&self) -> bool
where __T: AssetMetaDyn,

Returns true if the trait object wraps an object of type __T.

source

pub fn downcast<__T>( self: Box<dyn AssetMetaDyn> ) -> Result<Box<__T>, Box<dyn AssetMetaDyn>>
where __T: AssetMetaDyn,

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

source

pub fn downcast_rc<__T>( self: Rc<dyn AssetMetaDyn> ) -> Result<Rc<__T>, Rc<dyn AssetMetaDyn>>
where __T: AssetMetaDyn,

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

source

pub fn downcast_ref<__T>(&self) -> Option<&__T>
where __T: AssetMetaDyn,

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

source

pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>
where __T: AssetMetaDyn,

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.
