Terminal capabilities detected from the replies to the queries Screen::init fires. Every field answers a single question: does the terminal support this? The facade intercepts the reply events as they flow through read_event / try_read_event, records support here, and applies the render-affecting ones — the app never sees the reply events. Read back with Screen::capabilities.

Fields

synchronized_output: bool

Synchronized output (DEC private mode 2026). Applied: frames are wrapped in begin/end-synchronized-update markers.

grapheme_clusters: bool

Unicode core / grapheme-cluster mode (DEC private mode 2027). Applied: cell widths are measured per grapheme cluster.

in_band_resize: bool

In-band resize notifications (DEC private mode 2048).

mouse_normal: bool

Normal mouse button tracking (DEC private mode 1000).

mouse_button: bool

Button-event mouse tracking (DEC private mode 1002).

mouse_any: bool

Any-event mouse tracking (DEC private mode 1003).

mouse_sgr: bool

SGR mouse encoding (DEC private mode 1006).

mouse_sgr_pixel: bool

SGR-pixel mouse encoding (DEC private mode 1016).

sixel: bool

Sixel graphics (Primary DA attribute 4).

clipboard: bool

Clipboard access (Primary DA attribute 52).

kitty_keyboard: bool

Kitty keyboard protocol (the terminal answered CSI ? u).

modify_other_keys: bool

xterm modifyOtherKeys (the terminal answered CSI ? 4 m).

true_color: bool

Direct (24-bit) color, confirmed by an XTGETTCAP RGB/Tc reply. Applied: the renderer’s color profile is upgraded to Profile::TrueColor.

Trait Implementations

impl Clone for Capabilities

fn clone(&self) -> Capabilities

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Capabilities

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Capabilities

fn default() -> Capabilities

Returns the “default value” for a type.

impl PartialEq for Capabilities

fn eq(&self, other: &Capabilities) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Capabilities

impl Eq for Capabilities

impl StructuralPartialEq for Capabilities
