Trait rustdct::Dst7

pub trait Dst7<T: DctNum>: RequiredScratch + Length + Sync + Send {
    fn process_dst7_with_scratch(&self, buffer: &mut [T], scratch: &mut [T]);

    fn process_dst7(&self, buffer: &mut [T]) { ... }
}

A trait for algorithms which compute the Discrete Cosine Transform Type 7 (DST7)

Required methods

fn process_dst7_with_scratch(&self, buffer: &mut [T], scratch: &mut [T])

Computes the DST Type 7 on the provided buffer, in-place. Uses the provided scratch buffer as scratch space.

Does not normalize outputs.

Provided methods

fn process_dst7(&self, buffer: &mut [T])

Computes the DST Type 7 on the provided buffer, in-place.

This method may allocate a Vec of scratch space as needed. If you’d like to reuse that allocation between multiple computations, consider calling process_dst7_with_scratch instead.

Does not normalize outputs.
