The JS-facing key object — a 1:1 mirror of ink’s Key type (use-input.ts:9-124), NOT the lower-level parseKeypress output. napi-rs renames each snake_case field to the camelCase ink name automatically (up_arrow → upArrow, …); return is a Rust keyword so it is the raw identifier r#return, which napi still emits as return. The FIELD-NAME-EXACT covenant (M3-F) is asserted by the spike via Object.keys.

Fields

up_arrow: bool

down_arrow: bool

left_arrow: bool

right_arrow: bool

page_down: bool

page_up: bool

home: bool

end: bool

return: bool

escape: bool

ctrl: bool

shift: bool

tab: bool

backspace: bool

delete: bool

meta: bool

super_key: bool

hyper: bool

caps_lock: bool

num_lock: bool

event_type: Option<String>

Kitty event type: "press", "repeat", or "release"; None for legacy (non-kitty) keys, mirroring ink’s optional eventType.

Trait Implementations

This function called to convert napi values to native rust values

fn from_unknown(value: Unknown<'_>) -> Result<Self, Error>

impl ToNapiValue for Key

unsafe fn to_napi_value(env: napi_env, val: Key) -> Result<napi_value>

This function called to convert rust values to napi values

fn into_unknown(self, env: &Env) -> Result<Unknown<'_>, Error>

impl TypeName for Key

fn type_name() -> &'static str

fn value_type() -> ValueType

impl ValidateNapiValue for Key

unsafe fn validate( env: *mut napi_env__, napi_val: *mut napi_value__, ) -> Result<*mut napi_value__, Error>

This function called to validate whether napi value passed to rust is valid type.
