Trait rustdct::Dct3 [−][src]
pub trait Dct3<T: DctNum>: RequiredScratch + Length + Sync + Send {
fn process_dct3_with_scratch(&self, buffer: &mut [T], scratch: &mut [T]);

}Expand description
A trait for algorithms which compute the Discrete Cosine Transform Type 3 (DCT3)
Required methods
fn process_dct3_with_scratch(&self, buffer: &mut [T], scratch: &mut [T])
fn process_dct3_with_scratch(&self, buffer: &mut [T], scratch: &mut [T])
Computes the DCT Type 3 on the provided buffer, in-place. Uses the provided scratch buffer as scratch space.
Does not normalize outputs.
Provided methods
fn process_dct3(&self, buffer: &mut [T])
fn process_dct3(&self, buffer: &mut [T])
Computes the DCT Type 3 on the provided buffer, in-place.
This method may allocate a Vecprocess_dct3_with_scratch instead.
Does not normalize outputs.
