Struct vsdb::basic::orphan::Orphan

pub struct Orphan<T> { /* private fields */ }

Used to express some ‘non-collection’ types, such as any type of integer, an enum value, etc..

Implementations

impl<T> Orphan<T> where
    T: ValueEnDe, 

pub fn new(v: T) -> Self

pub fn get_value(&self) -> T

Get the inner cloned value.

pub fn get_mut(&self) -> ValueMut<'_, T>

NOTE:

• Always use this method to change value
  • *(<Orphan>).get_mut() = ...
• NEVER do this:
  • *(&mut <Orphan>) = Orphan::new(...)
