Struct wrapped_mono::Exception

pub struct Exception { /* private fields */ }

Safe representation of MonoException.

Implementations

impl Exception

pub unsafe fn raise(&self) -> !

Raise exception (it can be then cached by catch clause in managed code)

Safety

This function is extremely unsafe, because when it is called, drop functions of local variables are not automatically called.

Example

C#

 using System.Runtime.CompilerServices;
 class SomeClass{
     [MethodImplAttribute(MethodImplOptions.InternalCall)]   
     void ExceptionThrower();
     void SomeMethod(){
         try{
             ExceptionThrower();
         }
         catch(exception){
             Console.WriteLine("This will always catch exceptions raised in ExceptionThrower");
         }
     }
 }

Rust

 #[invokable]
 fn exception_thrower(){
     let some_local_data = vec![12,2,35,32];
     let exception = Exception::not_implemented("This function will just throw exceptions!");
     // Everything needs to be dropped before exception is thrown!
     drop(some_local_data);
     unsafe{exception.raise()};
 }

Trait Implementations

impl Clone for Exception

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Exception

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for Exception

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl InteropClass for Exception

fn get_mono_class() -> Class

impl ObjectTrait for Exception

unsafe fn from_ptr_unchecked(exc_ptr: *mut MonoObject) -> Self

Creates new instance of Self from *mut [MonoObject]. Pointer is guaranteed to be not null, and of type which can be assigned to managed type represented by Self.

fn get_ptr(&self) -> *mut MonoObject

Gets the internal [MonoObject] pointer.

fn cast<Target: ObjectTrait>(&self) -> Option<Target>

unsafe fn from_ptr(obj_ptr: *mut MonoObject) -> Option<Self>

Creates new instance of Self from *mut [MonoObject]. Returns None if either obj_ptr is null OR object obj_ptr points to is of a type which does not derive from the managed type Self represents.

fn hash(&self) -> i32

get hash of this object: This hash is not based on values of objects fields, and differs from result of calling object.GetHash()

fn get_domain(&self) -> Domain

get Domain this object exists in.

fn get_size(&self) -> u32

get size of managed object referenced by self in bytes. Does include builtin hidden data.

fn get_class(&self) -> Class

Returns Class of this object. NOTE: This is function returns the class of the underlying object, not class represented by Self. This means that class returned from get_class may be a class derived from class Self represents.

fn to_mstring(&self) -> Result<Option<MString>, Exception>

Returns result of calling ToString on this Object.

impl<O: ObjectTrait> PartialEq<O> for Exception

fn eq(&self, other: &O) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
