Trait ForEach

pub trait ForEach<T> {
    type Ref<'a>;

    // Required methods
    fn for_each<F>(&self, for_each: F) -> CallbackHandle
       where F: for<'a> FnMut(Self::Ref<'a>) + Send + 'static;
    fn for_each_subsequent<F>(&self, for_each: F) -> CallbackHandle
       where F: for<'a> FnMut(Self::Ref<'a>) + Send + 'static;
}

A type that can have a for_each operation applied to it.

Required Associated Types

type Ref<'a>

The borrowed representation of T to pass into the for_each function.

Required Methods

fn for_each<F>(&self, for_each: F) -> CallbackHandle

where F: for<'a> FnMut(Self::Ref<'a>) + Send + 'static,

Invokes for_each with the current contents and each time this source’s contents are updated.

fn for_each_subsequent<F>(&self, for_each: F) -> CallbackHandle

where F: for<'a> FnMut(Self::Ref<'a>) + Send + 'static,

Attaches for_each to this value so that it is invoked each time the source’s contents are updated.

for_each will not be invoked with the currently stored value.

Object Safety

This trait is not object safe.
