Trait ComponentSource

Source 
pub trait ComponentSource: ComponentLayout {
    // Required methods
    fn is_empty(&mut self) -> bool;
    fn len(&self) -> usize;
    fn write<T: Iterator<Item = Entity>>(
        &mut self,

        chunk: &mut ComponentStorage,
    ) -> usize;
}
Expand description

A set of components to be attached to one or more entities.

Required Methods§

Source

fn is_empty(&mut self) -> bool

Determines if this component source has any more entity data to write.

Source

fn len(&self) -> usize

Retrieves the nubmer of entities in this component source.

Source

fn write<T: Iterator<Item = Entity>>( &mut self, entities: T, chunk: &mut ComponentStorage, ) -> usize

Writes as many components as possible into a chunk.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
