Struct opencv::core::Exception

pub struct Exception { /* private fields */ }

! 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 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.

Trait Implementations

impl Boxed for Exception

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

Wrap the specified raw pointer

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

Return the underlying raw pointer while consuming this wrapper.

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

Return the underlying raw pointer.

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

Return the underlying mutable raw pointer
