Implementations

impl cp_layer_renderer_state

pub const paused: Self

A state that indicates the layer renderer isn’t currently drawing.

A layer renderer starts in this state and later transitions to the running or invalid states. Don’t draw while in this state. Wait until the layer changes to one of the other states to take further action on the layer.

pub const running: Self

A state that indicates the layer renderer is ready for you to draw your content.

When the layer enters this state, start your rendering loop and draw your content. Keep drawing frames of content until the layer transitions to another state.

pub const invalidated: Self

A state that indicates the layer renderer no longer supports drawing operations.

A layer enters this state shortly before the system releases its resources. When the layer enters this state, exit your rendering loop and release any drawing-related structures.

Trait Implementations

impl Clone for cp_layer_renderer_state

fn clone(&self) -> cp_layer_renderer_state

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for cp_layer_renderer_state

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

Formats the value using the given formatter.

impl Encode for cp_layer_renderer_state

const ENCODING: Encoding = u32::ENCODING

The Objective-C type-encoding for this type.

impl Hash for cp_layer_renderer_state

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 Ord for cp_layer_renderer_state

fn cmp(&self, other: &cp_layer_renderer_state) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for cp_layer_renderer_state

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

impl PartialOrd for cp_layer_renderer_state

fn partial_cmp(&self, other: &cp_layer_renderer_state) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
