Struct FlexItemStyle

pub struct FlexItemStyle {
    pub flex_grow: f32,
    pub flex_shrink: f32,
    pub flex_basis: Length,
    pub align_self: Option<AlignItems>,
}

Flex item style for a child of Row / Column (flex_grow, align_self, …).

Examples

use ailloli_ui_core::style::{AlignItems, FlexItemStyle};
let item = FlexItemStyle::new().flex_grow(1.0).align_self(AlignItems::Center);
assert_eq!(item.flex_grow, 1.0);

Fields

flex_grow: f32

Non-negative share of remaining main-axis space; default 0.0.

flex_shrink: f32

Non-negative shrink weight under deficit; default 0.0.

flex_basis: Length

Preferred main-axis size before grow/shrink; default Length::Auto.

align_self: Option<AlignItems>

Child-specific cross-axis alignment, or None to inherit the container.

Implementations

impl FlexItemStyle

pub fn new() -> Self

Creates a non-growing, non-shrinking item with automatic basis/alignment.

Examples

use ailloli_ui_core::style::{FlexItemStyle, Length};
assert_eq!(FlexItemStyle::new().flex_basis, Length::Auto);

pub fn flex_grow(self, value: f32) -> Self

Sets the grow factor, clamped to at least zero.

NaN and negative infinity become zero through floating-point max semantics; positive infinity remains infinite.

Examples

use ailloli_ui_core::style::FlexItemStyle;
assert_eq!(FlexItemStyle::new().flex_grow(-1.0).flex_grow, 0.0);

pub fn flex_shrink(self, value: f32) -> Self

Sets the shrink factor, clamped to at least zero.

NaN and negative infinity become zero through floating-point max semantics; positive infinity remains infinite.

Examples

use ailloli_ui_core::style::FlexItemStyle;
assert_eq!(FlexItemStyle::new().flex_shrink(2.0).flex_shrink, 2.0);

pub fn flex_basis(self, value: impl Into<Length>) -> Self

Replaces the preferred main-axis basis.

Examples

use ailloli_ui_core::style::{FlexItemStyle, Length};
assert_eq!(FlexItemStyle::new().flex_basis(20.0).flex_basis, Length::Px(20.0));

pub fn align_self(self, value: AlignItems) -> Self

Overrides the container’s cross-axis alignment for this child.

Examples

use ailloli_ui_core::style::{AlignItems, FlexItemStyle};
assert_eq!(FlexItemStyle::new().align_self(AlignItems::End).align_self, Some(AlignItems::End));

Trait Implementations

impl Clone for FlexItemStyle

fn clone(&self) -> FlexItemStyle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FlexItemStyle

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

Formats the value using the given formatter.

impl Default for FlexItemStyle

fn default() -> FlexItemStyle

Returns the “default value” for a type.

impl PartialEq for FlexItemStyle

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