Enum TxClass 

pub enum TxClass {
    Class2D = 0,
    ClassHoriz = 1,
    ClassVert = 2,
}

Transform class (for coefficient scan order).

Variants

Class2D = 0

2D transform (default scan).

ClassHoriz = 1

Horizontal class (column identity).

ClassVert = 2

Vertical class (row identity).

Implementations

impl TxClass

pub const fn count() -> usize

Get the number of transform classes.

pub const fn from_u8(val: u8) -> Option<Self>

Convert from integer.

Trait Implementations

impl Clone for TxClass

fn clone(&self) -> TxClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TxClass

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

Formats the value using the given formatter.

impl Default for TxClass

fn default() -> TxClass

Returns the “default value” for a type.

impl PartialEq for TxClass

fn eq(&self, other: &TxClass) -> 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 Copy for TxClass

impl Eq for TxClass

impl StructuralPartialEq for TxClass
