Enum OverflowBehavior 

pub enum OverflowBehavior {
    Clip,
    Visible,
    Scroll {
        max_content: Option<u16>,
    },
    Wrap,
}

How a layout container handles content that exceeds available space.

This enum models the CSS overflow property for terminal layouts. The actual clipping or scrolling is performed by the render layer; this value acts as a declarative hint attached to Flex or Grid so that widgets and the renderer know how to treat overflow regions.

Migration rationale

Web components routinely set overflow: hidden, overflow: scroll, etc. Without an explicit model the migration code emitter cannot faithfully translate these semantics. This enum bridges that gap.

Variants

Clip

Content that exceeds the container is clipped at the boundary. This is the safe default for terminals where drawing outside an allocated region corrupts neighbouring widgets.

Visible

Content is allowed to overflow visually (useful for popovers, tooltips, and hit-test regions that extend beyond their container).

Scroll

Content is clipped but a scrollbar region is reserved. The max_content field, when set, tells the scrollbar how large the virtual content area is.

Fields

max_content: Option<u16>

Size of the virtual content area in the overflow direction. None means “determine from content measurement”.

Wrap

Items that don’t fit are wrapped to the next row/column. Only meaningful for Flex containers.

Trait Implementations

impl Clone for OverflowBehavior

fn clone(&self) -> OverflowBehavior

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for OverflowBehavior

impl Debug for OverflowBehavior

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

Formats the value using the given formatter.

impl Default for OverflowBehavior

fn default() -> OverflowBehavior

Returns the “default value” for a type.

impl Eq for OverflowBehavior

impl Hash for OverflowBehavior

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OverflowBehavior

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