1//! [`Moves`]: which built-in moves may run in one step. An [`Ability`](super::Ability)
2//! clears what its own move rules out in [`Ability::before`](super::Ability::before): no
3//! dash while attacking, no wall grab while carrying, slow walking while pushing.
4
5/// Which built-in moves may run this step, and how fast running may go. Every step starts
6/// from [`Moves::ALL`]; abilities narrow it before the built-in moves run.
7///
8/// A cleared move doesn't start, and one in progress lets go where that makes sense (a
9/// climb without `climb` lets go of the wall, a glide without `glide` folds). Presses
10/// stay buffered as usual, so a jump pressed while `jump` was cleared can still fire once
11/// it is back within the buffer.
