Trait toad_stem::StemCellInternal

    // Required methods

A mutable memory location

This is used to back the behavior of Stem, which should be used instead of this trait.

Required Methods

fn new(t: T) -> Selfwhere Self: Sized,

Create an instance of Self

fn map_ref<F, R>(&self, f: F) -> Rwhere F: for<'a> FnMut(&'a T) -> R,

Map a reference to T to a new type

Implementors may choose to panic or block if map_mut called concurrently.

fn map_mut<F, R>(&self, f: F) -> Rwhere F: for<'a> FnMut(&'a mut T) -> R,

Map a mutable reference to T to a new type

Implementors may choose to panic or block if map_ref or map_mut called concurrently.
