Implementations§

impl TransformType

pub fn dct_select_size(self) -> (u32, u32)

Returns the size of the transform type, in 8x8 blocks.

pub fn need_transpose(&self) -> bool

Returns whether DCT coefficients should be transposed.

Trait Implementations§

impl Clone for TransformType

fn clone(&self) -> TransformType

Returns a copy of the value. Read more

1.0.0 · source§

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

Performs copy-assignment from source. Read more

impl Debug for TransformType

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