Struct efficient_enum::option::EfficientOptionTupleInnerNone

pub struct EfficientOptionTupleInnerNone<'a, A: 'a, B: 'a, TM: 'a = TagMSB>(_)
 where
    A: TaggableValue<TM, Two>;

A helper type useful for accessing the lack of data or replacing it with nothing without having to use unwraps.

Methods

impl<'a, TM, A, B> EfficientOptionTupleInnerNone<'a, A, B, TM> where
    A: TaggableValue<TM, Two>, 

fn clone_0(&self) -> A where
    A: Clone, 

Clones the A value

fn add_1(self, b: B) -> EfficientOptionTupleInnerSome<'a, A, B, TM>

Adds a B value

fn map<R, F: FnOnce(&mut A) -> R>(&mut self, f: F) -> R

Maps the A value to a result
