Implementations

impl BlockSize

pub const BLOCK_SIZES_ALL: usize = 22usize

pub const BLOCK_SIZES: usize = 16usize

pub fn from_width_and_height_opt( w: usize, h: usize, ) -> Result<BlockSize, InvalidBlockSize>

Errors

• Returns InvalidBlockSize if the given w and h do not produce a valid block size.

pub fn from_width_and_height(w: usize, h: usize) -> BlockSize

Panics

• If the given w and h do not produce a valid block size.

pub fn cfl_allowed(self) -> bool

pub const fn width(self) -> usize

pub const fn area(self) -> usize

width * height

pub const fn width_log2(self) -> usize

pub const fn width_mi_log2(self) -> usize

pub const fn width_mi(self) -> usize

pub fn height_imp_b(self) -> usize

pub const fn tx_size(self) -> TxSize

pub const fn subsampled_size( self, xdec: usize, ydec: usize, ) -> Result<BlockSize, InvalidBlockSize>

Source: Subsampled_Size (AV1 specification section 5.11.38)

Errors

• Returns InvalidBlockSize if the given block size cannot be subsampled in the requested way.

pub fn largest_chroma_tx_size(self, xdec: usize, ydec: usize) -> TxSize

Panics

Will panic if the subsampling is not possible

pub const fn is_sqr(self) -> bool

pub const fn is_sub8x8(self, xdec: usize, ydec: usize) -> bool

pub const fn sub8x8_offset(self, xdec: usize, ydec: usize) -> (isize, isize)

pub const fn subsize( self, partition: PartitionType, ) -> Result<BlockSize, InvalidBlockSize>

Errors

• Returns InvalidBlockSize if the block size cannot be split in the requested way.

pub const fn is_rect_tx_allowed(self) -> bool

Trait Implementations

impl Clone for BlockSize

fn clone(&self) -> BlockSize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockSize

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

Formats the value using the given formatter.

impl Display for BlockSize

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

Formats the value using the given formatter.

impl PartialEq for BlockSize

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

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