Struct InputState 

pub struct InputState { /* private fields */ }

Tracks the current state of all input devices (keyboard, mouse, touch) for a single game frame. The state should be updated by event handlers and cleared of per-frame data at the end of each frame.

Implementations

impl InputState

Implements input state management for InputState.

pub fn press_key(&mut self, key_code: String)

Records a key press event, adding to keys_pressed and keys_held.

Arguments

• String - The key code string (e.g., "KeyA", "Space").

pub fn release_key(&mut self, key_code: String)

Records a key release event, moving from keys_held to keys_released.

Arguments

• String - The key code string.

pub fn is_key_pressed<K>(&self, key_code: K) -> bool

where K: AsRef<str>,

Tests whether a key was pressed during this frame.

Arguments

• K - The key code string.

Returns

• bool - True if the key was pressed this frame.

pub fn is_key_held<K>(&self, key_code: K) -> bool

where K: AsRef<str>,

Tests whether a key is currently held down.

Arguments

• K - The key code string.

Returns

• bool - True if the key is held.

pub fn is_key_released<K>(&self, key_code: K) -> bool

where K: AsRef<str>,

Tests whether a key was released during this frame.

Arguments

• K - The key code string.

Returns

• bool - True if the key was released this frame.

pub fn press_mouse_button(&mut self, button: MouseButton, position: Vector2D)

Records a mouse button press at the given position.

Arguments

• MouseButton - The button that was pressed.
• Vector2D - The mouse position.

pub fn release_mouse_button(&mut self, button: MouseButton)

Records a mouse button release.

Arguments

• MouseButton - The button that was released.

pub fn update_mouse_position(&mut self, position: Vector2D)

Updates the mouse position and computes the delta from the previous position.

Arguments

• Vector2D - The new mouse position.

pub fn is_mouse_button_pressed(&self, button: MouseButton) -> bool

Tests whether a mouse button was pressed during this frame.

Arguments

• MouseButton - The button to check.

Returns

• bool - True if the button was pressed this frame.

pub fn is_mouse_button_held(&self, button: MouseButton) -> bool

Tests whether a mouse button is currently held down.

Arguments

• MouseButton - The button to check.

Returns

• bool - True if the button is held.

pub fn update_touch(&mut self, identifier: i32, position: Vector2D)

Adds or updates a touch point.

Arguments

• i32 - The touch identifier.
• Vector2D - The touch position.

pub fn start_touch(&mut self, identifier: i32, position: Vector2D)

Records a new touch point that started this frame.

Arguments

• i32 - The touch identifier.
• Vector2D - The touch position.

pub fn end_touch(&mut self, identifier: i32)

Removes a touch point and marks it as ended this frame.

Arguments

• i32 - The touch identifier.

pub fn primary_touch_position(&self) -> Option<Vector2D>

Returns the position of the lowest-identifier active touch point.

Pointer-style consumers (the example pages’ interactive demos) treat the primary touch like a mouse cursor: touch events never update mouse_position, so this accessor is the only public way to read a touch position.

Returns

• Option<Vector2D> - The client-space position of the primary touch, or None when no touch is active.

pub fn end_frame(&mut self)

Clears all per-frame input data (pressed, released, deltas).

Should be called at the end of each game frame after all input has been processed.
