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 SparseMat) -> Result<SparseMatIterator>

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

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

the copy constructor

Trait Implementations

impl Boxed for SparseMatIterator

unsafe fn from_raw(ptr: *mut c_void) -> Self

Wrap the specified raw pointer

fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

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

Return the underlying mutable raw pointer

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 self) -> *mut u8

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

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

moves iterator to the previous element

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 node(&self) -> Result<SparseMat_Node>

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

impl SparseMatIteratorTrait for SparseMatIterator

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

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

moves iterator to the next element

impl SparseMatIteratorTraitConst for SparseMatIterator

fn as_raw_SparseMatIterator(&self) -> *const c_void

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

returns pointer to the current sparse matrix node. it.node->idx is the index of the current element (do not modify it!)
