Struct MonoClass 

pub struct MonoClass(/* private fields */);

An opaque handle to a Mono runtime object.

Thread safety

This type is intentionally !Send + !Sync. Every thread that reads or writes Mono objects must first be registered with the runtime via crate::MonoThreadGuard::attach. Using a handle on an unregistered thread is undefined behavior — Mono’s garbage collector and internal bookkeeping assume all active threads are known to the runtime.

Handles are therefore bound to the thread on which they were obtained. The compiler enforces this: a handle cannot be moved to another thread without explicit unsafe code.

If you need to transfer a handle across thread boundaries and you can guarantee that both threads are attached to the runtime for the entire duration of use, you can opt in manually on your wrapper type:

struct MyComponent {
    class: mono_rt::MonoClass,
}

// SAFETY: `class` is only accessed while the calling thread holds a
// `MonoThreadGuard`, ensuring it is registered with the Mono runtime.
unsafe impl Send for MyComponent {}
unsafe impl Sync for MyComponent {}

Implementations

impl MonoClass

pub fn as_ptr(self) -> *mut c_void

pub fn from_ptr(ptr: *mut c_void) -> Option<Self>

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

Safety

ptr must be non-null and valid on a thread attached to the Mono runtime.

impl MonoClass

pub fn field(self, name: &str) -> Result<Option<MonoClassField>>

Looks up a field by name on this class.

Errors

Returns MonoError::NullByteInName if name contains an interior null byte. Returns MonoError::Uninitialized if the Mono API has not been initialized.

pub fn method( self, name: &str, param_count: Option<i32>, ) -> Result<Option<MonoMethod>>

Looks up a method by name on this class.

param_count restricts the search to a specific arity; pass None to match any overload.

Errors

Returns MonoError::NullByteInName if name contains an interior null byte. Returns MonoError::Uninitialized if the Mono API has not been initialized.

pub fn mono_type(self) -> Result<Option<MonoType>>

Returns the MonoType descriptor for this class.

Errors

Returns MonoError::Uninitialized if the Mono API has not been initialized.

pub fn vtable(self, domain: MonoDomain) -> Result<Option<MonoVTable>>

Returns the vtable for this class in the given domain.

Errors

Returns MonoError::Uninitialized if the Mono API has not been initialized.

pub fn new_object(self, domain: MonoDomain) -> Result<Option<MonoObject>>

Allocates a new uninitialized instance of this class in the given domain.

The returned object is not yet constructed — call the .ctor method via MonoMethod::invoke to initialize it.

Errors

Returns MonoError::Uninitialized if the Mono API has not been initialized.

pub fn fields(self) -> Result<Vec<MonoClassField>>

Returns all fields declared on this class.

Errors

Returns MonoError::Uninitialized if the Mono API has not been initialized.

pub fn methods(self) -> Result<Vec<MonoMethod>>

Returns all methods declared on this class.

Errors

Returns MonoError::Uninitialized if the Mono API has not been initialized.
