Struct opencv::core::SparseMatIterator

pub struct SparseMatIterator { /* private fields */ }

Read-write Sparse Matrix Iterator

The class is similar to cv::SparseMatConstIterator, but can be used for in-place modification of the matrix elements.

Implementations

impl SparseMatIterator

pub fn default() -> Result<SparseMatIterator>

the default constructor

pub fn new(_m: &mut impl SparseMatTrait) -> Result<SparseMatIterator>

the full constructor setting the iterator to the first sparse matrix element

pub fn copy(it: &impl SparseMatIteratorTraitConst) -> Result<SparseMatIterator>

the copy constructor

Trait Implementations

impl Boxed for SparseMatIterator

unsafe fn from_raw( ptr: <SparseMatIterator as OpenCVType<'_>>::ExternReceive ) -> Self

Wrap the specified raw pointer

fn into_raw( self ) -> <SparseMatIterator as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> <SparseMatIterator as OpenCVTypeExternContainer>::ExternSend

Return the underlying raw pointer.

fn as_raw_mut( &mut self ) -> <SparseMatIterator as OpenCVTypeExternContainer>::ExternSendMut

Return the underlying mutable raw pointer

impl Debug for SparseMatIterator

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

Formats the value using the given formatter.

impl Drop for SparseMatIterator

fn drop(&mut self)

Executes the destructor for this type.

impl From<SparseMatIterator> for SparseMatConstIterator

fn from(s: SparseMatIterator) -> Self

Converts to this type from the input type.

impl SparseMatConstIteratorTrait for SparseMatIterator

fn as_raw_mut_SparseMatConstIterator(&mut self) -> *mut c_void

fn set_hashidx(&mut self, val: size_t)

fn ptr_mut(&mut self) -> *mut u8

unsafe fn set_ptr(&mut self, val: *const u8)

fn set(&mut self, it: &impl SparseMatConstIteratorTraitConst) -> Result<()>

the assignment operator

fn incr(&mut self) -> Result<SparseMatConstIterator>

moves iterator to the next element

fn seek_end(&mut self) -> Result<()>

moves iterator to the element after the last element

impl SparseMatConstIteratorTraitConst for SparseMatIterator

fn as_raw_SparseMatConstIterator(&self) -> *const c_void

fn m(&self) -> SparseMat

fn hashidx(&self) -> size_t

fn ptr(&self) -> *const u8

fn node(&self) -> Result<SparseMat_Node>

returns the current node of the sparse matrix. it.node->idx is the current element index
