Trait Implementations

impl Arbitrary for GlobalId

type Parameters = (<u64 as Arbitrary>::Parameters, <u64 as Arbitrary>::Parameters, <u64 as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = TupleUnion<((u32, Arc<Map<<u64 as Arbitrary>::Strategy, fn(_: u64) -> Self>>), (u32, Arc<Map<<u64 as Arbitrary>::Strategy, fn(_: u64) -> Self>>), (u32, Arc<Map<<u64 as Arbitrary>::Strategy, fn(_: u64) -> Self>>), (u32, Arc<fn() -> Self>))>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).
