Struct dicetest::Limit

pub struct Limit(pub u64);

The upper limit for the length of dynamic data structures generated with DieOnce and Die.

The implementor of DieOnce or Die is allowed to freely interpret or even ignore this value, but it’s recommended that the complexity of the value generation is in O(limit).

This parameter exists because the hardware of the testing machine is limited. For example a very big list could not fit in the memory or its generation could take too much time. With this parameter you can implement a generator for lists of arbitrary length and its user can choose an upper limit depending on his hardware.

Implementations

impl Limit

pub fn saturating_from_usize(usize: usize) -> Self

Uses the given usize as limit.

If the usize is greater than the largest u64 value, the function returns the largest u64 value as limit.

pub fn saturating_to_usize(self) -> usize

Returns the limit as usize.

If the limit is greater than the largest usize value, the function returns the largest usize value.
