Struct proptest::collection::SizeRange
[−]
[src]
pub struct SizeRange(_);
The minimum and maximum range/bounds on the size of a collection.
The interval must form a subset of [0, std::usize::MAX)
.
The Default
is 0..100
.
Methods
impl SizeRange
[src]
fn new(range: Range<usize>) -> Self
[src]
Creates a SizeBounds
from a Range<usize>
.
fn with<X>(self, and: X) -> (Self, X)
[src]
Merges self together with some other argument producing a product
type expected by some impelementations of A: Arbitrary
in
A::Parameters
. This can be more ergonomic to work with and may
help type inference.
fn lift<X: Default>(self) -> (Self, X)
[src]
Merges self together with some other argument generated with a
default value producing a product type expected by some
impelementations of A: Arbitrary
in A::Parameters
.
This can be more ergonomic to work with and may help type inference.
Trait Implementations
