Enum AlignmentSafety 

#[repr(u8)]
pub enum AlignmentSafety {
    Unsafe = 0,
    Safe = 1,
}

The overflow-position modifier per CSS Box Alignment §4.3.

Safe falls back to start-edge alignment when the alignment subject would overflow the alignment container, so the start of the content stays visible. Unsafe (the default) keeps the requested alignment even when that causes overflow at the start edge.

CSS only defines safe / unsafe against the position values start, end, flex-start, flex-end, center. The struct shape does not enforce that constraint at the type level — the parser rejects invalid combinations, and the compute pass treats Safe paired with a non-position keyword (Stretch, Baseline, Space*) the same as Unsafe.

Variants

Unsafe = 0

Default — keeps the requested alignment even when the subject overflows the alignment container at the start edge.

Safe = 1

Falls back to the start edge when the subject would overflow, to avoid data loss.

Trait Implementations

impl Clone for AlignmentSafety

fn clone(&self) -> AlignmentSafety

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AlignmentSafety

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

Formats the value using the given formatter.

impl PartialEq for AlignmentSafety

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