Struct un_algebra::tests::result::MaybeErrValueTree

pub struct MaybeErrValueTree<T, E>(_)
 where
    E: ValueTree,
    T: ValueTree;

ValueTree type corresponding to MaybeErr.

Trait Implementations

impl<T, E> Debug for MaybeErrValueTree<T, E> where
    E: Debug + ValueTree,
    T: Debug + ValueTree,
    <T as ValueTree>::Value: Debug,
    <E as ValueTree>::Value: Debug, 

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl<T, E> Clone for MaybeErrValueTree<T, E> where
    E: Clone + ValueTree,
    T: Clone + ValueTree,
    <T as ValueTree>::Value: Clone,
    <E as ValueTree>::Value: Clone, 

fn clone(&self) -> MaybeErrValueTree<T, E>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T, E> ValueTree for MaybeErrValueTree<T, E> where
    E: ValueTree,
    T: ValueTree, 

type Value = Result<<T as ValueTree>::Value, <E as ValueTree>::Value>

The type of the value produced by this ValueTree.

fn current(&self) -> <MaybeErrValueTree<T, E> as ValueTree>::Value

Returns the current value.

fn simplify(&mut self) -> bool

Attempts to simplify the current value. Notionally, this sets the "high" value to the current value, and the current value to a "halfway point" between high and low, rounding towards low.

fn complicate(&mut self) -> bool

Attempts to partially undo the last simplification. Notionally, this sets the "low" value to one plus the current value, and the current value to a "halfway point" between high and the new low, rounding towards low.
