Struct opencv::core::Exception

pub struct Exception { /* fields omitted */ }

! Class passed to an error.

This class encapsulates all or almost all necessary information about the error happened in the program. The exception is usually constructed and thrown implicitly via CV_Error and CV_Error_ macros.

Implementations

impl Exception

pub fn as_raw_Exception(&self) -> *const c_void

pub fn as_raw_mut_Exception(&mut self) -> *mut c_void

impl Exception

pub fn default() -> Result<Exception>

! Default constructor

pub fn new(
    _code: i32,
    _err: &str,
    _func: &str,
    _file: &str,
    _line: i32
) -> Result<Exception>

! Full constructor. Normally the constructor is not called explicitly. Instead, the macros CV_Error(), CV_Error_() and CV_Assert() are used.

impl Boxed for Exception

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

Wrap the specified raw pointer

pub fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

pub fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

Return the underlying mutable raw pointer
