🔬 This is a nightly-only experimental API. (step_trait #42168)

likely to be replaced by finer-grained traits

Objects that can be stepped over in both directions.

The steps_between function provides a way to efficiently compare two Step objects.

Required Methods

fn steps_between(start: &Self, end: &Self) -> Option<usize>

🔬 This is a nightly-only experimental API. (step_trait #42168)

likely to be replaced by finer-grained traits

Returns the number of steps between two step objects. The count is inclusive of start and exclusive of end.

Returns None if it is not possible to calculate steps_between without overflow.

fn replace_one(&mut self) -> Self

🔬 This is a nightly-only experimental API. (step_trait #42168)

likely to be replaced by finer-grained traits

Replaces this step with 1, returning itself

fn replace_zero(&mut self) -> Self

🔬 This is a nightly-only experimental API. (step_trait #42168)

likely to be replaced by finer-grained traits

Replaces this step with 0, returning itself

fn add_one(&self) -> Self

🔬 This is a nightly-only experimental API. (step_trait #42168)

likely to be replaced by finer-grained traits

Adds one to this step, returning the result

fn sub_one(&self) -> Self

🔬 This is a nightly-only experimental API. (step_trait #42168)

likely to be replaced by finer-grained traits

Subtracts one to this step, returning the result

fn add_usize(&self, n: usize) -> Option<Self>

🔬 This is a nightly-only experimental API. (step_trait #42168)

likely to be replaced by finer-grained traits

Add an usize, returning None on overflow
