Struct Insets 

pub struct Insets {
    pub top: u16,
    pub right: u16,
    pub bottom: u16,
    pub left: u16,
}

Defines the padding between a component’s outer area and its children’s content area.

Return Insets from Component::content_inset to reserve space for borders, padding, or other chrome. The framework renders children inside the inset region, while the component’s render method receives the full outer area to draw its chrome.

Construction

Insets::ZERO              // no insets (default)
Insets::all(1)            // 1-cell border on all sides
Insets::symmetric(1, 2)   // 1 top/bottom, 2 left/right
Insets::new().top(1).left(2)  // builder style

Fields

top: u16

Rows reserved above the content area.

right: u16

Columns reserved to the right of the content area.

bottom: u16

Rows reserved below the content area.

left: u16

Columns reserved to the left of the content area.

Implementations

impl Insets

pub const ZERO: Insets

No insets — children get the full area.

pub fn new() -> Self

Create zero insets (same as ZERO).

pub fn all(n: u16) -> Self

Uniform insets on all sides.

pub fn symmetric(vertical: u16, horizontal: u16) -> Self

Symmetric insets: vertical for top/bottom, horizontal for left/right.

pub fn top(self, v: u16) -> Self

Set the top inset.

pub fn bottom(self, v: u16) -> Self

Set the bottom inset.

pub fn left(self, v: u16) -> Self

Set the left inset.

pub fn right(self, v: u16) -> Self

Set the right inset.

pub fn horizontal(&self) -> u16

Total horizontal inset (left + right).

pub fn vertical(&self) -> u16

Total vertical inset (top + bottom).

Trait Implementations

impl Clone for Insets

fn clone(&self) -> Insets

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Insets

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

Formats the value using the given formatter.

impl Default for Insets

fn default() -> Insets

Returns the “default value” for a type.

impl PartialEq for Insets

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