Keys

:= []

Keys module - keyboard state and key constants.

Key state encoding uses one byte per key: - bit 0 = currently held - bit 1 = pressed this frame - bit 2 = released this frame

The host stores fixed-size state lists with one byte per raylib key code 0-348. Named keys cover the full raylib KeyboardKey enum. Use Raw(code) through from_code when you need a backend-specific escape hatch.

from_code : U64 -> Try(KeyboardKey, [InvalidKeyCode, ..])

Validate and wrap a raw raylib key code.

key_code : KeyboardKey -> U64

raylib key code for a key (index into the Host key-state lists).

key_down : { ..state, keys : List(U8) }, KeyboardKey -> Bool

Check if a specific key is currently held down. Pass host directly.

key_up : { ..state, keys : List(U8) }, KeyboardKey -> Bool

Check if a specific key is currently not pressed (up). Pass host directly.

key_pressed : { ..state, keys : List(U8) }, KeyboardKey -> Bool

Check if a key was first pressed this frame. Pass host directly.

key_released : { ..state, keys : List(U8) }, KeyboardKey -> Bool

Check if a key was released this frame. Pass host directly.
