Struct opencv::core::SparseMatConstIterator

pub struct SparseMatConstIterator { /* private fields */ }

Read-Only Sparse Matrix Iterator.

Here is how to use the iterator to compute the sum of floating-point sparse matrix elements:

\code SparseMatConstIterator it = m.begin(), it_end = m.end(); double s = 0; CV_Assert( m.type() == CV_32F ); for( ; it != it_end; ++it ) s += it.value(); \endcode

Implementations

impl SparseMatConstIterator

pub fn default() -> Result<SparseMatConstIterator>

the default constructor

pub fn new(_m: &impl SparseMatTraitConst) -> Result<SparseMatConstIterator>

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

pub fn copy( it: &impl SparseMatConstIteratorTraitConst ) -> Result<SparseMatConstIterator>

the copy constructor
