pub struct MatConstIterator { /* private fields */ }

/////////////////////////////// MatConstIterator //////////////////////////////////

Implementations

impl MatConstIterator

pub fn default() -> Result<MatConstIterator>

default constructor

pub fn over(_m: &impl MatTraitConst) -> Result<MatConstIterator>

constructor that sets the iterator to the beginning of the matrix

pub fn with_rows_cols( _m: &impl MatTraitConst, _row: i32, _col: i32 ) -> Result<MatConstIterator>

constructor that sets the iterator to the specified element of the matrix

C++ default parameters

• _col: 0

pub fn with_rows_cols_def( _m: &impl MatTraitConst, _row: i32 ) -> Result<MatConstIterator>

constructor that sets the iterator to the specified element of the matrix

Note

This alternative version of [with_rows_cols] function uses the following default values for its arguments:

• _col: 0

pub fn with_start( _m: &impl MatTraitConst, _pt: Point ) -> Result<MatConstIterator>

constructor that sets the iterator to the specified element of the matrix

pub fn copy(it: &impl MatConstIteratorTraitConst) -> Result<MatConstIterator>

copy constructor
