Struct WeakInstanceToken

Source

pub struct WeakInstanceToken {
    pub inner: Box<dyn WeakInstanceTokenAny>,
}

Expand description

A type representing a weak pointer to a component. This is type erased because the bedrock library shouldn’t depend on Component Manager types.

Fields§

§inner: Box<dyn WeakInstanceTokenAny>

Implementations§

Source §

impl WeakInstanceToken

Source

pub fn new_invalid() -> Arc<Self> ⓘ
