Struct FocusNode 

pub struct FocusNode {
    pub id: FocusId,
    pub bounds: Rect,
    pub tab_index: i32,
    pub is_focusable: bool,
    pub group_id: Option<u32>,
}

A focusable node in the graph.

Fields

id: FocusId

Unique identifier.

bounds: Rect

Bounding rectangle in terminal coordinates.

tab_index: i32

Tab index for sequential navigation. Negative values skip tab order.

is_focusable: bool

Whether this node can receive focus.

group_id: Option<u32>

Optional group for focus trapping regions.

Implementations

impl FocusNode

pub fn new(id: FocusId, bounds: Rect) -> Self

Create a new focusable node.

pub fn with_tab_index(self, idx: i32) -> Self

Builder: set tab index.

pub fn with_focusable(self, focusable: bool) -> Self

Builder: set focusable flag.

pub fn with_group(self, group: u32) -> Self

Builder: set group.

Trait Implementations

impl Clone for FocusNode

fn clone(&self) -> FocusNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FocusNode

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

Formats the value using the given formatter.

impl PartialEq for FocusNode

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