Struct flo_binding::BindRef

pub struct BindRef<Target> { /* fields omitted */ }

A BindRef references another binding without needing to know precisely what kind of binding it is. It is read-only, so mostly useful for passing a binding around, particularly for computed bindings. Create one with BindRef::from(binding).

Cloning a BindRef will create another reference to the same binding.

Methods

impl<Value> BindRef<Value>

pub fn new<Binding: 'static + Clone + Bound<Value>>(
    binding: &Binding
) -> BindRef<Value>

Creates a new BindRef from a reference to an existing binding

pub fn from_arc<Binding: 'static + Bound<Value>>(
    binding_ref: Arc<Binding>
) -> BindRef<Value>

Creates a new BindRef from an existing binding
