Struct LayerStack 

pub struct LayerStack { /* private fields */ }

Ordered layer stack metadata.

Implementations

impl LayerStack

pub fn new(layers: Vec<LayerRole>) -> LayerStack

pub fn layers(&self) -> &[LayerRole]

pub fn top(&self) -> Option<LayerRole>

pub fn is_above(&self, layer: LayerRole, other: LayerRole) -> bool

Trait Implementations

impl Clone for LayerStack

fn clone(&self) -> LayerStack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayerStack

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

Formats the value using the given formatter.

impl Default for LayerStack

fn default() -> LayerStack

Returns the “default value” for a type.

impl PartialEq for LayerStack

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