Struct CMTimeRoundingMethod 

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

Available on crate feature CMTime only.

Rounding method to use when computing time.value during timescale conversions.

away from 0 if abs(fraction) is >= 0.5.

from larger to smaller scale (ie. from more precision to less precision), but use kCMTimeRoundingMethod_RoundAwayFromZero if converting from smaller to larger scale (ie. from less precision to more precision). Also, never round a negative number down to 0; always return the smallest magnitude negative CMTime in this case (-1/newTimescale).

Trait Implementations

impl Clone for CMTimeRoundingMethod

fn clone(&self) -> CMTimeRoundingMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CMTimeRoundingMethod

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

Formats the value using the given formatter.

impl Encode for CMTimeRoundingMethod

Available on crate feature objc2 only.

const ENCODING: Encoding = u32::ENCODING

The Objective-C type-encoding for this type.

impl Hash for CMTimeRoundingMethod

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 CMTimeRoundingMethod

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

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

fn partial_cmp(&self, other: &CMTimeRoundingMethod) -> 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 RefEncode for CMTimeRoundingMethod

Available on crate feature objc2 only.

const ENCODING_REF: Encoding

The Objective-C type-encoding for a reference of this type.
