Graphics-related terminal capabilities resolved for the current process.

Fields

id: TerminalId

Detected terminal emulator.

charset: Charset

Glyph capability tier inferred from the emulator (OMP_TUI_CHARSET overrides).

graphics: Graphics

Safe image rendering mode.

kitty_placeholders: bool

Whether Kitty Unicode placeholders are trusted for this terminal.

cell_px: Option<(u16, u16)>

Pixel width and height of one terminal cell, when reported.

sixel_color_registers: Option<u16>

Number of SIXEL color registers reported by XTSMGRAPHICS.

sync_output: bool

Whether DEC synchronized output mode 2026 is supported.

kitty_keyboard: Option<u8>

Kitty keyboard protocol flags reported by the terminal.

screen_to_scrollback: bool

Whether cleared viewport content can be moved to native scrollback.

margin_scrollback: bool

Whether rows scrolled out of a top-anchored DECSTBM region enter native scrollback.

hyperlinks: bool

Whether OSC 8 hyperlinks are supported.

text_sizing: bool

Whether Kitty OSC 66 text sizing is supported.

deccara: bool

Whether Kitty-style DECCARA rectangular SGR is supported.

notify: NotifyProtocol

Notification protocol selected for this terminal.

osc99_confirmed: bool

Whether a Kitty OSC 99 capability reply confirmed rich notifications.

background: Option<(u16, u16, u16)>

Terminal background color normalized to 16-bit RGB components.

appearance_notifications: bool

Whether DEC mode 2031 appearance notifications are supported.

in_band_resize: bool

Whether DEC mode 2048 in-band resize notifications are supported.

paste_events: bool

Whether DEC mode 5522 enhanced paste offers are supported.

xterm_scroll_to_bottom_on_output: bool

Whether xterm mode 1010 was set and may be temporarily disabled.

xterm_scroll_to_bottom_on_key_press: bool

Whether xterm mode 1011 was set and may be temporarily disabled.

jamo_width: u8

Hangul Compatibility Jamo width, or zero for the platform default.

inside_tmux: bool

Whether the process is inside tmux.

inside_multiplexer: bool

Whether a tmux, screen, Zellij, Herdr, or cmux marker was detected.

Implementations

impl TerminalCaps

pub fn resolve( env_caps: Self, probe: Option<&ProbeResults>, forced: Option<Graphics>, ) -> Self

Resolves an explicit override, runtime replies, and environment fallback.

Explicit overrides win unchanged. A probe that received at least one recognizable reply supersedes environment protocol guesses. tmux can carry Kitty APC and SIXEL DCS through passthrough; other multiplexers conservatively disable non-forced graphics.

Trait Implementations

impl Clone for TerminalCaps

fn clone(&self) -> TerminalCaps

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TerminalCaps

impl Debug for TerminalCaps

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

Formats the value using the given formatter.

impl Eq for TerminalCaps

impl PartialEq for TerminalCaps

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

Equality operator ==.

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

Inequality operator !=.
