Struct PaneFocusRing 

pub struct PaneFocusRing {
    pub border: BorderChars,
    pub cell: Cell,
}

A stable focus indicator: a distinct border drawn around the active pane.

Fields

border: BorderChars

Border glyph set (default: double-line, visually distinct from pane content borders).

cell: Cell

Cell whose fg/bg/attrs style the border glyphs.

Implementations

impl PaneFocusRing

pub fn themed(affordance: &PaneAffordanceTheme) -> Self

Build a focus ring whose color is the theme’s contrast-guaranteed pane focus-ring affordance (bd-3bfbp).

The supplied PaneAffordanceTheme has already been contrast-clamped against the pane surface (AA by default, AAA when built in the high-contrast profile), so the ring stays visible across every theme without per-call tuning.

Trait Implementations

impl Clone for PaneFocusRing

fn clone(&self) -> PaneFocusRing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PaneFocusRing

impl Debug for PaneFocusRing

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

Formats the value using the given formatter.

impl Default for PaneFocusRing

fn default() -> Self

Returns the “default value” for a type.

impl Eq for PaneFocusRing

impl PartialEq for PaneFocusRing

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