Struct Anchor 

pub struct Anchor {
    pub top: bool,
    pub bottom: bool,
    pub left: bool,
    pub right: bool,
}

Anchor edges for layer surface positioning.

When opposite edges are anchored (e.g., left + right), the surface stretches to fill that axis. When only one edge is anchored, the surface is placed at that edge with its requested size.

Fields

top: bool

bottom: bool

left: bool

right: bool

Implementations

impl Anchor

pub fn none() -> Self

Create an Anchor with no edges set.

pub fn from_bits(bits: u32) -> Self

Create an Anchor from a bitfield (protocol wire format).

Bit 0 = top, bit 1 = bottom, bit 2 = left, bit 3 = right.

pub fn to_bits(&self) -> u32

Convert to bitfield representation.

pub fn stretches_horizontal(&self) -> bool

Whether this anchor stretches horizontally (left + right).

pub fn stretches_vertical(&self) -> bool

Whether this anchor stretches vertically (top + bottom).

Trait Implementations

impl Clone for Anchor

fn clone(&self) -> Anchor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Anchor

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

Formats the value using the given formatter.

impl PartialEq for Anchor

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