Enum MvPrecision 

#[repr(u8)]
pub enum MvPrecision {
    FullPel = 0,
    HalfPel = 1,
    QuarterPel = 2,
    EighthPel = 3,
}

Motion vector precision levels.

Variants

FullPel = 0

Full pixel precision (integer pel).

HalfPel = 1

Half pixel precision (1/2 pel).

QuarterPel = 2

Quarter pixel precision (1/4 pel).

EighthPel = 3

Eighth pixel precision (1/8 pel).

Implementations

impl MvPrecision

pub const fn fractional_bits(self) -> u8

Returns the number of fractional bits for this precision.

pub const fn scale(self) -> i32

Returns the scale factor for sub-pixel units.

pub const fn frac_mask(self) -> i32

Returns the mask for extracting fractional part.

pub const fn convert(self, value: i32, target: Self) -> i32

Converts a value from this precision to another.

Trait Implementations

impl Clone for MvPrecision

fn clone(&self) -> MvPrecision

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MvPrecision

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

Formats the value using the given formatter.

impl Default for MvPrecision

fn default() -> MvPrecision

Returns the “default value” for a type.

impl Hash for MvPrecision

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 MvPrecision

fn eq(&self, other: &MvPrecision) -> 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.
