Rounding methods.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AV_ROUND_ZERO = 0

< Round toward zero.

AV_ROUND_INF = 1

< Round away from zero.

AV_ROUND_DOWN = 2

< Round toward -infinity.

AV_ROUND_UP = 3

< Round toward +infinity.

AV_ROUND_NEAR_INF = 5

< Round to nearest and halfway cases away from zero.

AV_ROUND_PASS_MINMAX = 8_192

Flag telling rescaling functions to pass INT64_MIN/MAX through unchanged, avoiding special cases for #AV_NOPTS_VALUE.

Unlike other values of the enumeration AVRounding, this value is a bitmask that must be used in conjunction with another value of the enumeration through a bitwise OR, in order to set behavior for normal cases.

@code{.c} av_rescale_rnd(3, 1, 2, AV_ROUND_UP | AV_ROUND_PASS_MINMAX); // Rescaling 3: // Calculating 3 * 1 / 2 // 3 / 2 is rounded up to 2 // => 2

av_rescale_rnd(AV_NOPTS_VALUE, 1, 2, AV_ROUND_UP | AV_ROUND_PASS_MINMAX); // Rescaling AV_NOPTS_VALUE: // AV_NOPTS_VALUE == INT64_MIN // AV_NOPTS_VALUE is passed through // => AV_NOPTS_VALUE @endcode

Trait Implementations

impl Clone for AVRounding

fn clone(&self) -> AVRounding

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AVRounding

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

Formats the value using the given formatter.

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 PartialEq for AVRounding

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
