Function compute_released_buttons 

pub fn compute_released_buttons(
    previous_held: &GamepadButtonSet,
    values: &[f64],
) -> GamepadButtonSet

Folds one frame of raw gamepad readings into the per-pad edge sets.

The held set this frame is every button at or above half pressure; the released set is every button that was held last frame and is no longer down, which is what a caller polls with to fire a one-shot action on button-up.

Arguments

• &GamepadButtonSet - The previous frame’s held button indices.
• &[f64] - This frame’s raw button pressure per button index.

Returns

• GamepadButtonSet - The buttons that came up on this frame.
