Struct PaneCapabilityMatrix 

pub struct PaneCapabilityMatrix {
    pub mux: PaneMuxEnvironment,
    pub mouse_sgr: bool,
    pub mouse_drag_reliable: bool,
    pub mouse_button_discrimination: bool,
    pub focus_events: bool,
    pub bracketed_paste: bool,
    pub unicode_box_drawing: bool,
    pub true_color: bool,
    pub degraded: bool,
}

Resolved capability matrix describing which pane interaction features are available in the current terminal + multiplexer environment.

Derived from [TerminalCapabilities] via PaneCapabilityMatrix::from_capabilities. The adapter uses this to decide which code-paths are safe and which need deterministic fallbacks.

Fields

mux: PaneMuxEnvironment

Detected multiplexer environment.

mouse_sgr: bool

SGR (1006) extended mouse protocol available. Without this, mouse coordinates are limited to 223 columns/rows.

mouse_drag_reliable: bool

Mouse drag events are reliably delivered. False in some screen versions where drag tracking is incomplete.

mouse_button_discrimination: bool

Mouse button events include correct button identity on release. X10/normal mode sends button 3 for all releases; SGR preserves it.

focus_events: bool

Terminal delivers CSI I / CSI O focus events.

bracketed_paste: bool

Bracketed paste mode available (affects interaction cancel heuristics).

unicode_box_drawing: bool

Unicode box-drawing glyphs available for splitter rendering.

true_color: bool

True-color support for splitter highlight/drag feedback.

degraded: bool

One or more pane features are degraded due to environment constraints.

Implementations

impl PaneCapabilityMatrix

pub fn from_capabilities(caps: &TerminalCapabilities) -> Self

Derive the pane capability matrix from terminal capabilities.

This is the single source of truth for which pane features are available. All fallback decisions flow from this matrix.

pub const fn drag_enabled(&self) -> bool

Whether pane drag interactions should be enabled at all.

Drag requires at minimum mouse event support. If drag events are unreliable (e.g. GNU Screen), drag is disabled and the adapter falls back to keyboard-only resize.

pub const fn focus_cancel_effective(&self) -> bool

Whether focus-loss auto-cancel is effective.

When focus events are unavailable, the adapter cannot detect window blur — interactions must rely on timeout or explicit keyboard cancel instead.

pub fn limitations(&self) -> Vec<PaneCapabilityLimitation>

Collect all active limitations with their fallback descriptions.

Trait Implementations

impl Clone for PaneCapabilityMatrix

fn clone(&self) -> PaneCapabilityMatrix

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PaneCapabilityMatrix

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

Formats the value using the given formatter.

impl PartialEq for PaneCapabilityMatrix

fn eq(&self, other: &PaneCapabilityMatrix) -> 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.
