Struct AVRounding

#[repr(transparent)]
pub struct AVRounding(pub i32);

Rounding methods used in FFmpeg’s av_rescale_rnd function.

These rounding modes determine how values are rounded during scaling operations.

See the official FFmpeg documentation: https://ffmpeg.org/doxygen/trunk/group__lavu__math__rational.html

Implementations

impl AVRounding

pub const Zero: Self

Round toward zero (truncate fractional part).

• Example: 2.9 -> 2, -2.9 -> -2
• Equivalent to: AV_ROUND_ZERO

pub const AwayFromZero: Self

Round away from zero.

• Example: 2.1 -> 3, -2.1 -> -3
• Equivalent to: AV_ROUND_INF

pub const Down: Self

Round toward negative infinity.

• Example: 2.9 -> 2, -2.1 -> -3
• Equivalent to: AV_ROUND_DOWN

pub const Up: Self

Round toward positive infinity.

• Example: 2.1 -> 3, -2.9 -> -2
• Equivalent to: AV_ROUND_UP

pub const NearestAwayFromZero: Self

Round to the nearest integer, with halfway cases rounded away from zero.

• Example: 2.5 -> 3, -2.5 -> -3
• Equivalent to: AV_ROUND_NEAR_INF

pub const PassMinMax: Self

Pass INT64_MIN / INT64_MAX unchanged during rescaling.

Bitmask flag (must be combined with another rounding mode).

• Example:

  av_rescale_rnd(3, 1, 2, AV_ROUND_UP | AV_ROUND_PASS_MINMAX);

• Equivalent to: AV_ROUND_PASS_MINMAX

Trait Implementations

Formats the value using the given formatter.

impl From<AVRounding> for i32

fn from(value: AVRounding) -> Self

Converts to this type from the input type.

fn from(value: AVRounding) -> Self

Converts to this type from the input type.

impl Hash for AVRounding

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 AVRounding

fn cmp(&self, other: &AVRounding) -> 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<i32> for AVRounding

fn eq(&self, other: &i32) -> 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 PartialEq for AVRounding

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

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