Struct TupleValueTree

Source
pub struct TupleValueTree<T> { /* private fields */ }
Expand description

Common ValueTree implementation for all tuple strategies.

Implementations§

Source§

impl<T> TupleValueTree<T>

Source

pub fn new(inner: T) -> Self

Create a new TupleValueTree wrapping inner.

It only makes sense for inner to be a tuple of an arity for which the type implements ValueTree.
