Struct ItemBoxStyle 

pub struct ItemBoxStyle {
    pub section_header_rows: u16,
    pub card_border_rows: u16,
    pub card_border_cols: u16,
    pub focus_indicator_cols: u16,
    pub description_right_padding_cols: u16,
}

Visual style for a setting item: tunes every dimension of the layout so chrome (card border, padding, section header, indicator gutter) can be toggled or tweaked from one place.

All values are in terminal cells (rows or columns). Setting a row/col count to 0 disables that piece of chrome; the rest of the layout still works.

Fields

section_header_rows: u16

Rows occupied by a section header: title row + blank gap below it. Set to 0 to suppress section headings entirely.

card_border_rows: u16

Top/bottom border thickness of the per-item card (rows).

card_border_cols: u16

Left/right border thickness of the per-item card (columns).

focus_indicator_cols: u16

Columns reserved on the left of the card’s interior for the focus indicator (>), the modified marker (●), and a single-space gutter.

description_right_padding_cols: u16

Right-side padding inside the card so wrapped description text doesn’t butt up against the right border.

Implementations

impl ItemBoxStyle

pub const fn cards() -> Self

The default look used by the settings panel: 1-row top/bottom card borders, 1-col side borders, 2-row section headers.

pub const fn flat() -> Self

A flat look with no card border. Items still get 1-row gap chrome (carried by the section header) and the indicator gutter.

pub fn inner_text_width(&self, card_outer_width: u16) -> u16

Width available for wrapped description text inside a card of the given outer width (subtracting both borders, the focus gutter, and the right padding).

Trait Implementations

impl Clone for ItemBoxStyle

fn clone(&self) -> ItemBoxStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ItemBoxStyle

impl Debug for ItemBoxStyle

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

Formats the value using the given formatter.

impl Default for ItemBoxStyle

fn default() -> Self

Returns the “default value” for a type.

impl Eq for ItemBoxStyle

impl PartialEq for ItemBoxStyle

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