ludus::input¶

Distinguishes a focus enter (synchronize held set, no edges) from the various cancellation paths and the two explicit modes. ExplicitLive keeps the current physical baseline focused; ExplicitNeutral installs an empty, unfocused baseline.

Constants and variables¶

TRACE_CAPACITY¶

constexpr usize ludus::input::TRACE_CAPACITY = 256

Related types: usize

Declared in modules/input/include/ludus/input/input_debug.h

KEY_COUNT¶

constexpr usize ludus::input::KEY_COUNT = static_cast<usize>(Key::Count)

Number of dense key slots, including the reserved Unknown slot at index 0.

Related types: usize

Declared in modules/input/include/ludus/input/key.h

PENDING_CAPACITY¶

constexpr usize ludus::input::PENDING_CAPACITY = 256

Fixed capacities (frozen in M0).

Pending transitions queued between steps, the output step-event buffer, and the action/binding domains. Overflow of the pending ring is a bounded, observable loss event, never growth or a crash.

Related types: usize

Declared in modules/input/include/ludus/input/keyboard.h

ACTION_CAPACITY¶

constexpr usize ludus::input::ACTION_CAPACITY = 64

Related types: usize

BINDING_CAPACITY¶

constexpr usize ludus::input::BINDING_CAPACITY = 256

Related types: usize

Declared in modules/input/include/ludus/input/keyboard.h

Functions¶

IsValidKey¶

constexpr bool ludus::input::IsValidKey(Key key) noexcept

True when key is a real, in-range key that may index key storage.

Unknown is deliberately NOT valid for indexing gameplay state: it is a sink value. This rejects fabricated enum values above Count as well as Unknown.

Related types: Key

Declared in modules/input/include/ludus/input/key.h

KeyIndex¶

constexpr usize ludus::input::KeyIndex(Key key) noexcept

Dense index for a validated key. The caller MUST have checked IsValidKey.

Related types: usize · Key

Declared in modules/input/include/ludus/input/key.h

DebugLabel¶

const char * ludus::input::DebugLabel(Key key) noexcept

Stable physical debug label (e.g. "KeyW", "ShiftLeft").

Never a layout- or locale-dependent character. Returns "Unknown" for Unknown or any value that is not a real key. Intended for diagnostics/trace, not gameplay.
