Struct KeepConstraint 

pub struct KeepConstraint {
    pub keep_together: Keep,
    pub keep_with_next: Keep,
    pub keep_with_previous: Keep,
}

Keep constraint for page breaking

Represents the XSL-FO keep properties that control page breaking behavior.

Examples

use fop_layout::layout::{Keep, KeepConstraint};

let mut constraint = KeepConstraint::new();
constraint.keep_together = Keep::Always;
assert!(constraint.must_keep_together());

constraint.keep_with_next = Keep::Always;
assert!(constraint.must_keep_with_next());

Fields

keep_together: Keep

keep-together.within-page

keep_with_next: Keep

keep-with-next.within-page

keep_with_previous: Keep

keep-with-previous.within-page
