Struct FrameCount

pub struct FrameCount(pub u32);

Maintains a count of frames rendered since the start of the application.

FrameCount is incremented during Last, providing predictable behavior: it will be 0 during the first update, 1 during the next, and so forth.

Overflows

FrameCount will wrap to 0 after exceeding u32::MAX. Within reasonable assumptions, one may exploit wrapping arithmetic to determine the number of frames that have elapsed between two observations – see u32::wrapping_sub().

Tuple Fields

0: u32

Trait Implementations

impl Clone for FrameCount

fn clone(&self) -> FrameCount

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FrameCount

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

Formats the value using the given formatter.

impl Default for FrameCount

fn default() -> FrameCount

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FrameCount

Available on crate feature serialize only.

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Ord for FrameCount

fn cmp(&self, other: &FrameCount) -> 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 FrameCount

fn eq(&self, other: &FrameCount) -> 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 FrameCount

fn partial_cmp(&self, other: &FrameCount) -> 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.

impl Serialize for FrameCount

Available on crate feature serialize only.

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Copy for FrameCount

impl Eq for FrameCount

impl Resource for FrameCount

where Self: Send + Sync + 'static,
