Enum Constraint 

pub enum Constraint {
    Percentage(f32),
    Fixed(u16),
    Range {
        min: u16,
        max: u16,
    },
    Min(u16),
    Max(u16),
    Flexible,
}

Defines a constraint for sizing elements within a layout.

Constraints determine how much space an element should occupy relative to the available space or other elements.

Variants

Percentage(f32)

Takes up a specified percentage of the total available space (0.0 to 100.0). It will shrink if necessary to fit within the available space.

Fixed(u16)

Takes up a fixed amount of space in units (e.g., characters or rows). If the available space is less than the fixed size, an error may occur.

Range

Takes up space within a specified minimum and maximum range. It will try to fit its content but won’t go below min or above max.

Fields

min: u16

max: u16

Min(u16)

Takes up at least the specified minimum space, but can grow beyond it.

Max(u16)

Takes up at most the specified maximum space, but can shrink below it.

Flexible

Takes up all the remaining available space after other constraints have been resolved. Multiple flexible constraints will share the remaining space evenly.

Trait Implementations
