Struct proptest::strategy::TupleUnion [−][src]
#[must_use = "strategies do nothing unless used"]pub struct TupleUnion<T>(_);
Similar to Union
, but internally uses a tuple to hold the strategies.
This allows better performance than vanilla Union
since one does not need
to resort to boxing and dynamic dispatch to handle heterogeneous
strategies.
Methods
impl<T> TupleUnion<T>
[src]
impl<T> TupleUnion<T>
pub fn new(tuple: T) -> Self
[src]
pub fn new(tuple: T) -> Self
Wrap tuple
in a TupleUnion
.
The struct definition allows any T
for tuple
, but to be useful, it
must be a 2- to 10-tuple of (u32, impl Strategy)
pairs where all
strategies ultimately produce the same value. Each u32
indicates the
relative weight of its corresponding strategy.
You may use W<S>
as an alias for (u32, S)
.
Using this constructor directly is discouraged; prefer to use
prop_oneof!
since it is generally clearer.
