Struct FlexItem 

pub struct FlexItem {
    pub base: f32,
    pub grow: f32,
    pub shrink: f32,
    pub min: f32,
    pub max: f32,
}

Flex parameters for one item along a container’s main axis.

Fields

base: f32

Base size before growing or shrinking.

grow: f32

Relative weight used to claim free space.

shrink: f32

Relative weight used to absorb a deficit.

min: f32

Minimum size the item may shrink to.

max: f32

Maximum size the item may grow to.

Implementations

impl FlexItem

pub fn new(base: f32, grow: f32, shrink: f32, min: f32, max: f32) -> Self

Creates a sanitized flex item.

Non-finite or negative values are clamped: base and min to zero, grow to zero, shrink to one, and max becomes infinity when it is NaN or positive infinity.
