Enum PyramidLevel 

pub enum PyramidLevel {
    Anchor = 0,
    L1 = 1,
    L2 = 2,
    L3 = 3,
}

The role a frame plays within the B-pyramid hierarchy.

Variants

Anchor = 0

Top-level anchor frame (P or I); level 0 has highest quality.

L1 = 1

Level-1 B-frame (references two anchors).

L2 = 2

Level-2 B-frame (references two level-1 frames).

L3 = 3

Level-3 B-frame (leaf; references two level-2 frames).

Implementations

impl PyramidLevel

pub fn qp_delta(self) -> i8

Returns the suggested QP delta relative to the top-level anchor.

Trait Implementations

impl Clone for PyramidLevel

fn clone(&self) -> PyramidLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PyramidLevel

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

Formats the value using the given formatter.

impl Ord for PyramidLevel

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

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

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