Enum AngleDelta 

#[repr(i8)]
pub enum AngleDelta {
    Minus3 = -3,
    Minus2 = -2,
    Minus1 = -1,
    Zero = 0,
    Plus1 = 1,
    Plus2 = 2,
    Plus3 = 3,
}

Angle delta for AV1 directional modes.

AV1 allows fine-tuning directional prediction angles by -3 to +3 steps of 3 degrees each, giving a range of -9 to +9 degrees.

Variants

Minus3 = -3

-3 steps (-9 degrees)

Minus2 = -2

-2 steps (-6 degrees)

Minus1 = -1

-1 step (-3 degrees)

Zero = 0

No delta (0 degrees)

Plus1 = 1

+1 step (+3 degrees)

Plus2 = 2

+2 steps (+6 degrees)

Plus3 = 3

+3 steps (+9 degrees)

Implementations

impl AngleDelta

pub const STEP_DEGREES: i16 = 3

Angle step size in degrees.

pub const fn degrees(self) -> i16

Convert to degrees offset.

pub const fn from_steps(steps: i8) -> Option<Self>

Create from step count (-3 to +3).

pub const fn steps(self) -> i8

Convert to step count.

Trait Implementations

impl Clone for AngleDelta

fn clone(&self) -> AngleDelta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AngleDelta

impl Debug for AngleDelta

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

Formats the value using the given formatter.

impl Default for AngleDelta

fn default() -> AngleDelta

Returns the “default value” for a type.

impl Eq for AngleDelta

impl PartialEq for AngleDelta

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