Struct SwsVector 

pub struct SwsVector { /* private fields */ }

Implementations

impl SwsVector

pub fn as_ptr(&self) -> *const SwsVector

pub fn as_mut_ptr(&mut self) -> *mut SwsVector

pub unsafe fn set_ptr(&mut self, ptr: NonNull<SwsVector>)

Safety

This function should only be called when the pointer is valid and the data it’s pointing to can be dropped.

pub unsafe fn from_raw(raw: NonNull<SwsVector>) -> Self

Safety

This function should only be called when the pointer is valid and the data it’s pointing to can be dropped.

pub fn into_raw(self) -> NonNull<SwsVector>

impl SwsVector

pub fn new(length: i32) -> Option<Self>

Allocate and return an uninitialized vector with length coefficients.

If length is bigger than INT_MAX / sizeof(double) or smaller than 0, None is returned.

pub fn get_gaussian_vec(variance: f64, quality: f64) -> Option<Self>

Return a normalized Gaussian curve used to filter stuff. quality = 3 is high quality, lower is lower quality.

pub fn scale(&mut self, scalar: f64)

Scale all the coefficients of a by the scalar value.

pub fn normalize(&mut self, height: f64)

Scale all the coefficients of a so that their sum equals height.

pub fn coeff(&self) -> &[f64]

pub fn coeff_mut(&mut self) -> &mut [f64]

Trait Implementations

impl Deref for SwsVector

type Target = SwsVector

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Drop for SwsVector

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Send for SwsVector

impl UnsafeDerefMut for SwsVector

unsafe fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value, unsafely.
