Struct cp_drawable_state 

#[repr(transparent)]
pub struct cp_drawable_state(pub u32);

Available on crate feature drawable only.

The state of ownership for the drawable.

Use these constants to determine whether the drawable is ready for you to use. When the drawable is in the cp_drawable_state_rendering state, you can begin drawing. Other states indicate the drawable is either busy or not assigned to a frame.

Trait Implementations

impl Clone for cp_drawable_state

fn clone(&self) -> cp_drawable_state

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for cp_drawable_state

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

Formats the value using the given formatter.

impl Encode for cp_drawable_state

const ENCODING: Encoding = u32::ENCODING

The Objective-C type-encoding for this type.

impl Hash for cp_drawable_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_drawable_state

fn cmp(&self, other: &cp_drawable_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_drawable_state

fn eq(&self, other: &cp_drawable_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_drawable_state

fn partial_cmp(&self, other: &cp_drawable_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.
