Enum cursive::view::SizeConstraint

pub enum SizeConstraint {
    Free,
    Full,
    Fixed(usize),
    AtMost(usize),
    AtLeast(usize),
}

Single-dimensional constraint on a view size.

This describes a possible behaviour for a BoxView.

Variants

Free

No constraint imposed, the child view's response is used.

Full

Tries to take all available space, no matter what the child needs.

Fixed(usize)

Always return the included size, no matter what the child needs.

AtMost(usize)

Returns the minimum of the included value and the child view's size.

AtLeast(usize)

Returns the maximum of the included value and the child view's size.

Methods

impl SizeConstraint

fn available(self, available: usize) -> usize

Returns the size to be given to the child.

When available is offered to the BoxView.

fn result(self, (result, available): (usize, usize)) -> usize

Returns the size the child view should actually use.

When it said it wanted result.
